1)Breaking a phosphodiester linkage (P-O bond)in ATP is an endothermic process.
2)Aerobic respiration produces ATP by glucose oxidation.
3)In cells the hydrolysis of ATP is linked to many reactant favored processes to make them product favored.
A) 1 only
B) 2 only
C) 3 only
D) 1 and 2
E) 1,2,and 3

Question

Quizplus · Accepted Answer

1) Breaking a phosphodiester linkage in ATP releases energy and is therefore exothermic, not endothermic.
2) Aerobic respiration involves the oxidation of glucose to produce ATP, making this statement correct.
3) The hydrolysis of ATP releases energy and is coupled with many cellular processes to drive them towards the favored product, making this statement correct. Therefore, statements 1, 2, and 3 are all correct.
