Question

ATP -> ADP is often coupled with ________ reactions, whereas ADP -> ATP is often coupled with ________ reactions.

Select all that apply. Which of the molecules shown below has the highest potential energy in its bonds? Select only ONE answer choice

You run a research laboratory at ASU that researches diseases related to cellular respiration. You’re particularly interested in a disease where patients present as very lethargic because they can’t produce enough ATP. In this particular case, it appears that there is an issue with their ability to convert glucose to glucose-6-phosphate, one of the steps in glycolysis (pictured below). The reaction is best described as a(n) _________________ reaction.

Group of answer choices

Spontaneous

Exergonic

Endergonic

Isogonic

Synthetic

You discover that the patients with the disease described in the previous question have severely reduced hexokinase enzyme production, which of the following would you expect to observe when comparing glucose-6-phosphate levels from a sample of their blood to normal levels seen in a healthy adult?

Group of answer choices

I wouldn’t expect the patient to have any glucose-6-phosphate present in their blood sample.

I would expect the patient to have normal levels of glucose-6-phosphate present in their blood sample.

I would expect the patient to have lower than normal levels of glucose-6-phosphate present in their blood sample.

I would expect the patient to have higher than normal levels of glucose-6-phosphate present in their blood sample.

Answer 1

Answer 1. Exergonic - Endergonic

Answer 2. Endergonic (To produce ATP)

Answer 3. Patient would have lower than normal level of Glucose 6 Phosphate

Note-

In an exergonic reaction, energy is released to the surroundings.

ATP is hydrolyzed to ADP in the reaction ATP+H2O→ADP+Pi+ free energy

In an endergonic reaction, energy is absorbed from the surroundings.

ADP is combined with a phosphate to form ATP

ADP+Pi+free energy→ATP+H2O.
