Flashcards

Glycolysis

A catabolic pathway that breaks down glucose into pyruvate, producing a small amount of ATP.

Glycogenesis

The anabolic pathway that synthesizes glycogen from glucose.

Gluconeogenesis

The anabolic pathway that synthesizes glucose from non-carbohydrate precursors.

Krebs Cycle
