Concept explainers
Interpretation:
How the energy releasing steps of glycolysis are reversed in gluconeogenesis has to be explained.
Concept Introduction:
Glycolysis: This is the
Gluconeogenesis: This process of synthesis of glucose or glycogen from non-carbohydrate sources is called gluconeogenesis.
Substrate for gluconeogenesis
- Glycogenic amino acid
- Glycerol
- Pyruvate
- Lactate
- Intermediate of TCA cycle.
