Why do cells convert the energy stored in the bonds of glucose into energy stored in the bonds of atp?

Answers

Why do cells convert the energy stored in the bonds of glucose into energy stored in the bonds of ATP? Glucose is not a usable energy source for most enzymes.Theenergy in the bonds of glucose can only be extracted by the enzymes of glycolysis and respiration.

Most enzymes can't get their power from glucose. The enzymes of glycolysis and respiration are the only processes that can get the energy out of the bonds of glucose.

Why is the energy stored in glucose transferred to ATP?

It is derived from the glucose that is present in the foods that you consume. Energy is stored in the chemical bonds that are present in glucose molecules. A process known as cellular respiration is what releases the energy that has been stored and changes it into a form that your cells can use. This happens after glucose has been digested and transferred to the cells in your body.

ATP has a very modest amount of usable energy, whereas the molecules that make up food (in the form of carbs) have far higher levels of energy. ATP is easily available to cells, in contrast to carbohydrate molecules, which must first be phosphorylated in order to release the energy that they contain. ATP may be used by cells immediately.

A.) brain stem

B.) frontal lobe

C.) cerebellum

D.) parietal lobe

Answers

The answer would be D. (The parietal lobe)

Answer:

Explanation:

The temperature pathway travels through the sensory tract, specifically the spinothalamic tract which is part of the somato-sensory tract (conscious sensation). The sensory pathway is an ascendent pathway that carries information from the periphery to the brain, in this case the sensation is the heat, which is felt at the finger, the sensation then travels upwards and enters the spinal cord at the cervical level and crosses the midline to the opposite side, then continues to the brain stem and finally to the parietal lobe, areas 3, 1, 2 (primary somatosensory area) where the information is processed.

The sound of a police siren that is moving away has (1) _____ wavelengths, and one that is approaching has (2) ______ wavelengths.

1) a. longer b. higher c. shorter

2) a. lower b. Longer c. shorter

Answers

FIRST one (shorter)

SECOND one (longer)

Answer;

A. Longer

C. Shorter

The sound of a police siren that is moving away has shorter wavelengths, and one that is approaching has longer wavelengths.

Explanation;The pitch of the sound heard depends on the frequency of the sound wave. A higher frequency corresponds to a high pitch. Therefore, when the police siren is approaching an observer, the observed frequency increases and thus the observer hears a higher pitch.Conversely, when the police siren is moving away from an observer, then the frequency decreases and thus, the pitch of the sound heard is lower.A higher frequency corresponds to a shorter wavelength, therefore, the shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound.
