26 Carbohydrate Metabolism Flashcards

Flashcards reviewing carbohydrate metabolism, glycolysis, ATP synthesis, and anabolic pathways.

Glycolysis

Cytosolic reactions that split glucose.

Citric acid cycle

Mitochondrial matrix reactions that breaks glucose further.

Oxidative phosphorylation

Energy used in oxidative-reduction reactions in inner mitochondrial membrane.

Electron transport chain (ETC)

Involves transfer of electrons between carriers that leads to ATP production.

Substrate level phosphorylation

Involves transfer of PO4³- from a phosphate containing molecule to ADP to form ATP.

Oxidative phosphorylation

Involves flow of electrons to generate ATP, resulting in more ATP than substrate level phosphorylation.

Glycolysis

Part of anaerobic catabolism.

Citric acid cycle and electron transport chain

Types of oxidative catabolism (cellular respiration).

Glycolysis

10 "Sugar splitting" cytosolic reactions.

Glycolysis

6 carbon glucose splits into two 3 carbon pyruvate molecules occurs in every cell of body.

Glycogenesis

An enzyme catalyzed reaction that adds glucose molecules to growing glycogen molecule. Most glycogen stored in liver and skeletal muscle.

Glycogenolysis

Breakdown of glycogen into glucose.

Gluconeogenesis

Synthesis of new glucose from non-carbohydrate molecules.
