17.3: Carbohydrate Metabolism
- Review carbohydrate metabolism.
Introduction
There are many metabolic pathways, processes, or reactions that are involved in the synthesis or degradation of carbohydrates and compounds formed from them. Please note that most of these pathways are not specific to carbohydrates only. For example, in gluconeogenesis certain (glucogenic) amino acids are used for synthesizing glucose if needed.
Overview of Terminology
-
Glycogenesis
- glycogen synthesis
-
Glycogenolysis
- glycogen breakdown
-
Gluconeogenesis
- synthesis of glucose from a non-carbohydrate source
-
Glycolysis
- breakdown of glucose to pyruvate
-
Transition Reaction
- conversion of pyruvate to acetyl-CoA
-
Krebs Cycle (also known as Citric Acid or Tricarboxylic acid (TCA) Cycle)
- acetyl-CoA combines with oxaloacetate to form citrate; ATP, NADH, and FADH 2 are produced in the cycle
-
Electron Transport Chain
- oxidative phosphorylation, producing ATP from NADH and FADH 2
