Answer:
The correct answer is option d. "begins the production of a new glycogen molecule with the reactions of glycogenin".
Explanation:
As the name implies, glycogenesis is the process at which glycogen is synthesized. This process takes place by binding and addition of multiple glucose molecules. Glycogenesis begins the production of a new glycogen molecule with the reactions of glycogenin, an enzyme that acts as a primer and catalyzes the polymerization of the first few glucose molecules.
