the Venn diagram compares aerobic and anaerobic respiration.
which statement could be categorized in the overlapping section of the Venn diagram?
A. uses pyruvic acid
B. has commercial uses
C. regenerates NADH
D. produces 36 ATP
Answers
The right answer is A. uses pyruvic acid
Pyruvate, the final product of glycolysis, follows different catabolic pathways according to the nature of the organism and the metabolic conditions.
- Lactic fermentation: anaerobic glycolysis in the muscle in contraction or in certain tissue types (brain, retina, erythrocytes).
- Alcoholic fermentation: anaerobic glycolysis in yeast and certain microorganisms.
- The oxidative decarboxylation followed by the Krebs cycle: oxidation of pyruvate to CO2 and H2O in animals, plants and many prokaryotic aerobic cells.
Ans.
Aerobic respiration involves complete breakdown of a glucose molecule in the presence of oxygen to generate energy, in the form of ATP molecules (36 molecules of ATP).
On the other hand, anaerobic respiration involves partial breakdown of a glucose molecule in the absence of oxygen to generate energy as ATP molecules (2 molecules of ATP).
The common feature, shared by both aerobic and anaerobic respiration is use of pyruvate (pyruvic acid). The pyruvic acid is formed by the process of glycolysis, which is common for both the processes.
In aerobic respiration, pyruvic acid is used to form acetyl coenzyme A that enters the Kreb's cycle, while during the anaerobic respiration, pyruvic acid is used to make alcohol or lactic acid to regenerate NAD+.
Thus, the correct answer is option A). 'uses pyruvic acid.'

Part a - the cell cycle drag the pink labels onto the pink targets to identify the two main phases of the cell cycle. then drag the blue labels onto the blue targets to identify the key stages that occur during those phases.
Answers
The two main stages of the cell cycle are interphase and M phase. Interphase is further segregated into G1, S, and G2 phase while the M phase is segregated into prophase, metaphase, anaphase, and telophase.
Further Explanation:
The cell cycle refers to an ordered flow of events which includes cell growth as well as cellular division. This cycle produces 2 new daughter cells. The cycle starts with interphase; during which, the cell grows and replicates its own DNA or deoxyribonucleic acid. The interphase begins with:
1. G1 phase: This is the primary growth phase provide nutrient to the cell.
2. S phase or synthesis of DNA: During this phase, the replication of DNA takes place. The centrosome is divide and forms mitotic spindle during the mitosis phase.
3. G2 or second gap: during this phase, the cell mainly replenishes its energy stores as well as synthesizes the proteins which are required for the chromosome manipulation.
The second phase of the cell cycle is the mitosis or M phase. Mitotic phase refers to a multiphase process during which the chromosomes are aligned, segregated, and moved into the 2 new daughter cells which are identical to each other.
This phase starts with:
1. Prophase: During this phase, the condensation of the chromosomes takes place and these chromosomes become visible. Spindle fibers formation take place, breakdown of the nuclear envelope, and nucleolus disappear.
2. Metaphase: During this phase, the formation of spindle fibers is completed and centrosomes are found at the opposite terminals of the cell. The chromosomes line up at the metaphase plate. Each of the sister chromatids is linked to the spindle fiber starting from the opposite poles.
3. Anaphase: During this phase, the cohesion proteins link with the sister chromatids and splits them down. The sister chromatids are pulled towards the opposite terminals of the cell and the non-kinetochore spindle fibers mainly lengthen and elongate the cell.
4. Telophase: During this last phase, the chromosomes arrive at the opposite terminals and start to decondense. Nuclear envelope reappears, and mitotic spindle breaks down. This marks the end of the mitosis.
The end phase of the cell cycle is called cytokinesis wherein the cleavage furrow occurs are segregates the daughter cells. In plant cells, the cell plate is responsible for the segregation of the daughter cells.

Carbon enters the soil when humans perform respiration and exhale it. /D. Carbon enters the soil when plants make glucose and deposit it into the soil.
whats the answer A/B/C OR /D
Answers
Carbon is deposited into the soil through decomposers which digests and generate carbon when organisms die and become buried beneath the soil. This process also is observed during the carbon cycle. Carbon cycle is a biogeochemical cycle where the transfer of carbon from the different spheres of the earth occurs. This involves the geosphere, hydrosphere, atmosphere, pedosphere and most especially, the biosphere.
Carbon enters the soil when plants make glucose and deposit it into the soil.
Explanation:The correct statement that explains how carbon enters the soil during the carbon cycle is Option D. Carbon enters the soil when plants make glucose and deposit it into the soil. During photosynthesis, plants convert carbon dioxide from the atmosphere into glucose, which is then used for growth or stored in the roots and leaves. As plants decay or are consumed by decomposers, the carbon is released back into the soil as organic matter.

What is respiration?Respiration is the process of releasing energy from food through oxidation. Aerobic along with anaerobic respiration are the two kinds of respiration.
Aerobic means "with air," and it refers to the body's use of oxygen to produce energy. This usually refers to any exercise that lasts more than two minutes.
Aerobic 'steady state' exercise is performed continuously. Anaerobic refers to the body producing energy without the use of oxygen.
The term anaerobic refers to cellular respiration that occurs in the absence of oxygen. In aerobic respiration, oxygen is the final electron acceptor.
Fermentation is the breakdown of organic molecules in the absence of oxygen. Yeast converts pyruvate to carbon dioxide and acetaldehyde during fermentation.
Aerobic respiration generates 34-38 ATP molecules, whereas anaerobic respiration generates only two.

Which area of the limbic system has considerable influence on the secretion of hormones throughout the body?
Answers
The hypothalamus.
The hypothalamus links the nervous system with the endocrine system. It's part of the limbic system but can also synthesizes and secretes hypothalamic hormones. These hormones will either stimulate or inhibit the pituitary gland, which releases hormones that go throughout the body to the glands and organs.
Hypothalamus is the part of the limbic system that has considerable influence on the secretion of hormones throughout the body.
Further Explanation:
The parts of the brain that are located under the temporal lobe sandwiching the thalamus collectively constitute the limbic system. The limbic system was first defined by Paul D. MacLean. The biggest area of the brain is occupied by the forebrain. The limbic system, the hypothalamus, thalamus, and the pineal gland are the structures of the forebrain. A tiny structure in the brain that is present just on the brain stem in between the cerebral cortex and midbrain is called the thalamus.
The part of the forebrain that lies beneath the thalamus is known as the hypothalamus. Hypothalamus means "under the thalamus" This part of the brain is responsible for the control and coordination of the autonomous nervous system, the pituitary gland secretion, the thirst, temperature and systems of homeostasis.
Two different sets of nerve cells that are present in the hypothalamus stimulates the production of the hormones. The maintenance of proper production of all the hormones is done by the gland. One set of the nerve cells transports the hormones produced by hypothalamus to the pituitary stalk from where the hormone is transported to the posterior lobe of the pituitary gland. These hormones (ADH and oxytocin) are then released in the bloodstream.
