Hexokinase is an enzyme that catalyzes the phosphorylation of glucose to produce glucose-1-phosphate.The reaction uses ATP as the source of phosphate, and ADP is the other product of the reaction.Each glucose-1-phosphate produced undergoes a series of reactions that lead to the formation of two pyruvate molecules, which contain three carbon atoms each.This is an example of a nucleotide functioning in
A) transfer of biological information.
B) breakdown of carbohydrates.
C) transport of cellular energy.
D) storage of cellular energy.
E) transfer of environmental information to cells.

Question

Quizplus · Accepted Answer

Hexokinase catalyzes the breakdown of glucose, which is a carbohydrate. Therefore, this is an example of a nucleotide functioning in the breakdown of carbohydrates. Choices A, C, D, and E are incorrect because they do not accurately describe the role of nucleotides in this process.
