C) two
D) three
E) four

Question

Quizplus · Accepted Answer

Two NTP (nucleoside triphosphate) molecules, specifically ATP, are used in the synthesis of glycogen from glucose. The first step of the process involves the conversion of glucose to glucose-6-phosphate, which requires one ATP molecule. The last step involves the transfer of a glucose residue from UDP-glucose to a growing glycogen chain, which requires another ATP molecule. Therefore, the net number of NTP molecules used in the synthesis of glycogen from glucose is two.
