Which has 1/or more catabolic pathway only?

Question

glycogenolysis

glycolysis

glycogenesis

krebs cycle

and is energy produced in absorptive phase..yes right?because al phases need energy

Answer 1

Catabolism means the breakdown of something.

*Glycogenolysis - lysis (breakdown) of glycogen

*Glycolysis - lysis (breakdown) of glucose)

Glycogenisis - gensis (creation) of glycogen

*Kreb Cycle - oxidation of citrate (break down of citrate)

*These are catabolic pathways.

Sorry, I really understand the question. But I think you mean, which one of these pathways has ONE beginning stubstrate. That would be Glycogenolysis. Glycogen --> Glucose --> Pyruvate....so on.

Glycolysis can begin with both glucose and glycogen.

Krebs can begin with fatty acids, amino acids, carbohydrates and so on.
