Professor PC Thomas Classes · Answer

(a) : Krebs' cycle also known as TCA cycle or citric acid cycle, is a common pathway of oxidative breakdown of carbohydrates, fatty acids and amino acids. Amino acids enter the Krebs' cycle directly as glutamate (for $\alpha$-ketoglutarate) and asparate (for oxaloacetate) after their deamination. Fats produce fatty acids and glycerol. Glycerol is phosphorylated and oxidised to form glyceraldehyde 3 -phosphate. Fatty acids undergo $\beta$-oxidation to produce acetyl CoA. Acetyl CoA enters Krebs' cycle.\
