Concept explainers
Interpretation:
The pyruvate cannot be converted to glucose in an exact reverse of the glycolysis pathway has to be explained.
Concept Introduction:
Glycolysis: This is one of biochemical pathway that breakdown a molecules of glucose into two molecules of pyruvate and producing for some energy.
Glycolysis occurs in the cytoplasm and has two major phases.
- Energy investment phase
- Energy payoff phase
These processes lactate from pyruvate in an animal organism and in a variety of microorganism in anaerobic conditions.
The conversion of glucose into lactate is called lactic acid formation,
