D. Fats regulate body functions, while enzymes denature invasive bacteria.

Explain why.

Answers

fats are storage molecules , while enzymes are catalytic molecules

Answer:

The correct answer is C. Fats are storage molecules, while enzymes are catalytic molecules.

Explanation:

Fats are primarily made up of carbon and hydrogen atoms which makes it hydrophobic in nature. Fat are macronutrient and they is stored on the liver which are utilized by the body in the scarcity of glucose and glycogen in the body. Fats can provide more calories that amino acids and glycogen after oxidation.

Enzymes are catalytic molecules that can regulate the reaction rate. Most of the enzymes increase the rate of the reaction and helps in completion of a metabolic process. Enzymes in the human body works more efficiently at 37°c.

Therefore fats are used for storage purpose and enzymes are used to catalyze a reaction. So the right answer is C.

Which are the major organ systems that undergo the compensation effect during anemia? select all that apply?

Answers

Respiratory system and Cardiovascular system.

Anemia is, by definition, low red blood cells or low hemoglobin. When anemia develops for a long period of time, our heart will have to increase its output, which means, it has to work harder to pump the blood and oxygen that it has, throughout the body. Meanwhile, the lungs are also compensating for the lack of oxygen and the excess of carbon dioxide coming from the cells, by increasing breathing rate.

Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.

Answers

The four organelles that should be present in the eukaryotic organism are: 1) Nucleus which contains the DNA and directs all of the activities of the cell 2) The Mitochondria which turns food in to energy 3) Ribosomes which make protein and 4) The Golgi Apparatus which processes the proteins.

Final answer:

The eukaryotic organism contains organelles such as the nucleus, mitochondria, endoplasmic reticulum, and the Golgi apparatus, which function in controlling cellular activity, producing energy, synthesizing proteins, and processing cellular products, respectively.

Explanation:

Four organelles that should be present in a eukaryotic organism and their functions are as follows:

Nucleus: Acts as the control center of the cell, housing the DNA and coordinating activities such as growth, metabolism, and reproduction.Mitochondria: Known as the powerhouses of the cell, mitochondria are where oxidative phosphorylation occurs to produce ATP, the cell's energy currency.Endoplasmic Reticulum (ER): Divided into rough ER, which is involved in protein synthesis and folding due to the presence of ribosomes, and smooth ER, which is important for lipid metabolism and detoxification processes.Golgi Apparatus: Functions in modifying, sorting, and packaging of proteins for secretion or use within the cell.

These organelles are crucial for the function and maintenance of eukaryotic cells, enabling the segregation of various biochemical processes.

Answer: The three-dimensional structure of a protein is determined by its amino acid sequence. Second, the function of a protein depends upon its three-dimensional structure. Third, the three-dimensional structure of a protein is unique, or nearly so. Fourth, the most important forces stabilizing the specific three-dimensional structure maintained by a given protein are noncovalent interactions. Finally, even though the structure of proteins is complicated, several common patterns can be recognized.

Types of molecules that interact with each other during the reaction.

Further explanation  

Enzymes are composed of 2 parts:

a. Apoenzim parts are enzymes composed of proteins. Apoenzim is a type that dominates from all kinds of enzyme structures. Its unstable nature is easily changed when influenced by temperature and pH.

b. Parts of prosthetic groups are enzymes arranged on the basis of nonprotein. Based on the constituent, prosthetic there are two more parts, namely:

Coenzyme: Its job is to transfer chemicals from one enzyme to another.

Cofactor: Its job is to optimize the ptialin enzyme in breaking down complex sugar molecules.

Like all proteins, enzymes are made for very long, linear chains of amino acids that are folded to produce a three-dimensional product. Each unique amino acid produces a specific structural sequence, which is unique. Individual protein chains are sometimes grouped together to form complex proteins. Most enzymes can be denatured, stretched and inactivated by heating or chemical denaturation, disrupting the structure of the three dimension proteins. Depending on the enzyme, denaturation may not be changed or reversible.

Enzymes have 4 properties, namely:

1. an enzyme resembling a protein

2. Enzymes work back and forth

3. Enzymes work specifically

4. Enzymes are biocatalysts

A woman in the third trimester of her first pregnancy expresses fear about the birth canal being wide enough for her to push the baby through it during labor. she is a petite person, and the baby seems so large. she asks the nurse how this will be possible. to help alleviate the client's fears, the nurse should mention the role of the hormone that softens the cervix and collagen in the joints, which allows dilation and enlargement of the birth canal. what is this hormone

Answers

relaxin

Relaxin, secreted by the corpus luteum of the ovary as well as the placenta, is responsible for helping to inhibit uterine activity and to soften the cervix and the collagen in joints. Softening of the cervix allows for dilatation at birth; softening of collagen allows for laxness in the lower spine and so helps enlarge the birth canal. The effect of estrogen is to cause breast and uterine enlargement. Progesterone has a major role in maintaining the endometrium, inhibiting uterine contractility, and aiding in the development of the breasts for lactation. Human placental lactogen (hPL), also known as human chorionic somatomammotropin, serves as an antagonist to insulin, making insulin less effective, thereby allowing more glucose to become available for fetal growth.

Know in great detail, how a muscle contraction occurs starting from calcium being released

Answers

The nerve impulses from the central nervous system cause the muscles in the human body to contract. When an impulse reaches the muscle fibers of a motor unit, it stimulates a reaction in each sarcomere that are located in between the myosin and the actin filaments.This reaction initiates a contraction. The head of the myosin filament reach forward and attach to the actin filament, pulling the actin towards the center of the sarcomere; this results in the shortening of the sarcomere. When the muscle is stimulated to contract by the nerve impulse, the calcium channel in the sarcoplasmic reticulum will be opened and calcium ions will be released into the sarcoplasm. Some of the released calcium will attach to troponin, this will cause a change in the muscle cells which move tropomyosin out of the way so that the cross bridge can link up and produce muscle contraction using ATP as energy source.

Which of these shows he correct order to the central dogma of molecular biology . Answer is D . DNA to RNA to protein . Why is the answer D ???

Answers

Answer:

The answer is D! Can you mark me brainliest? Im trying to level up.

Explanation:

The answer is D, DNA to RNA to protein, because this is the correct order of the central dogma of molecular biology, which describes the flow of genetic information within a biological system.

What enzyme is responsible for RNA making from DNA ?

In this process, DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid) by an enzyme called RNA polymerase, and then the RNA is translated into a protein by ribosomes.

This process is fundamental to all living organisms, and it allows for the transfer of genetic information from one generation to the next. The central dogma is a critical concept in molecular biology and is essential to understanding many biological processes, including genetic disorders and diseases.

The central dogma of molecular biology describes the flow of genetic information within a biological system. It states that DNA is transcribed into RNA, and RNA is translated into proteins. This process occurs in all living organisms and is essential for the function and survival of cells.

The correct order in the central dogma of molecular biology is DNA to RNA to protein. This means that DNA serves as a template for the synthesis of RNA molecules in a process called transcription. The RNA molecules are then transported from the nucleus to the cytoplasm, where they serve as templates for the synthesis of proteins in a process called translation.

The order of the central dogma is important because it ensures that genetic information is properly transmitted from DNA to proteins. Any errors or changes in this process can lead to mutations or other genetic disorders.

Therefore, understanding the central dogma is essential for understanding how genetic information is expressed in cells and how it can be manipulated for various applications in biology and medicine.

What type of information is used to direct different polypeptides to fold into different shapes?

Answers

Final answer:

The folding of different polypeptides into unique shapes is directed by their amino acid sequence. The type and position of these amino acids determine the final three-dimensional structure of the protein, which in turn influences its function.

Explanation:

The type of information that is used to direct different polypeptides to fold into different shapes is coded in the amino acid sequence of the polypeptide. This sequence influences how the polypeptide folds into its unique three-dimensional structure, which then determines its function. The shape of the polypeptide is extremely important as it determines the protein's activity and behavior in the cell. This folding process is influenced by the type of amino acids present and their relative positions in the sequence. For instance, hydrophobic amino acids usually tend to migrate towards the center of the protein, stabilizing the structure. Conversely, hydrophilic amino acids are found on the external surface of the protein, interacting with the surrounding water molecules in the cellular environment.

The type of information that is used to direct different polypeptides to fold into different shapes is the  sequence of amino acids  in the polypeptide.

The amino acid sequence determines the primary structure of the polypeptide, which is the linear sequence of amino acids.

The primary structure of the polypeptide determines its secondary structure, tertiary structure, and quaternary structure.

The secondary structure of a polypeptide is its three-dimensional structure as it folds back on itself. The secondary structure is stabilized by hydrogen bonds between the amino acids. The most common secondary structures are alpha helices and beta sheets.

The tertiary structure of a polypeptide is its three-dimensional structure in space. The tertiary structure is stabilized by a variety of interactions, including hydrogen bonds, ionic bonds, disulfide bonds, and hydrophobic interactions.

Here is an example of how the amino acid sequence influences the folding of a polypeptide:

The polypeptide hemoglobin contains a protein called globin. Globin is a globular protein, which means that it folds into a compact shape.

The globular shape of globin is essential for its function of carrying oxygen.

If the amino acid sequence of globin is changed, it can affect the way that the protein folds. For example, a mutation in the globin gene can cause a disease called sickle cell anemia.

In sickle cell anemia, the hemoglobin protein folds into a different shape, which makes it less effective at carrying oxygen.

The folding of polypeptides is a vital process for life. The shape of a polypeptide determines its function. By understanding how amino acid sequences influence the folding of polypeptides, scientists can better understand how proteins work and how to develop new treatments for diseases that are caused by protein misfolding.
