Which process converts glucose to glycogen for storage?

• A. Glycogenesis
• B. Glycolysis
• C. Lipolysis
• D. Glycogenolysis

Answer: (A)

Glycogenesis is the process that converts glucose into a storage form, glycogen, for quick later use. In the liver and skeletal muscles, glucose is linked together by glycogen synthase to form glycogen, with UDP-glucose providing the glucose units. This stored glycogen acts as a readily mobilizable reserve that helps maintain blood glucose levels and supplies energy during exercise.

Glycolysis, on the other hand, breaks down glucose to produce ATP; lipolysis breaks down fats; glycogenolysis breaks down glycogen back into glucose when energy is needed. So the conversion of glucose to glycogen for storage specifically points to glycogenesis.
