Quizplus · Accepted Answer

Gluconeogenesis is the metabolic process by which organisms produce glucose from non-carbohydrate precursors. Amino acids (from protein breakdown) and glycerol (from fat breakdown) can serve as substrates for gluconeogenesis, but glycogen is not a substrate for gluconeogenesis; instead, it is a storage form of glucose.
