Sort the following molecules based on the amount of energy that is released when their phosphate bond is hydrolyzed as indicated. Your answer would be a four-letter string composed of letters A to D only, e.g. ADCB. Put the molecule with the highest amount of hydrolysis energy on the left.
(A) ATP when hydrolyzed to ADP
(B) Glucose 6-phosphate when hydrolyzed to glucose
(C) 1,3-bisphosphoglycerate when hydrolyzed to 3-phosphoglycerate
(D) Phosphoenolpyruvate when hydrolyzed to pyruvate

Question

Sort the following molecules based on the amount of energy that is released when their phosphate bond is hydrolyzed as indicated. Your answer would be a four-letter string composed of letters A to D only, e.g. ADCB. Put the molecule with the highest amount of hydrolysis energy on the left.
(A)	ATP when hydrolyzed to ADP
(B)	Glucose 6-phosphate when hydrolyzed to glucose
(C)	1,3-bisphosphoglycerate when hydrolyzed to 3-phosphoglycerate
(D)	Phosphoenolpyruvate when hydrolyzed to pyruvate

Quizplus · Accepted Answer

Hydrolysis of phosphoenolpyruvate to pyruvate is the most exergonic (releases the highest amount of energy). ATP can be generated from ADP upon the hydrolysis of 1,3-bisphosphoglycerate to 3-phosphoglycerate. ATP hydrolysis can be used to drive the phosphorylation of glucose.
