<prompt> Pyridoxal phosphate is needed in:GlycogenolysisFatty acid oxidationGlvcogenesisGluconeogenesis  <response>: Ans-A Ref: Harpers Illustrated Biochemistry,28th edition Explanation: Glycogenolysis is the breakdown of glycogen. Glycogen Phosphorylase catalyzes the phosphorolytic cleavage of the l-4 glycosidic linkages of glycogen, releasing glucose-1- phosphate as the reaction product. Glycogen n residues Pi - glycogen n-1 residues glucose-1-phosphate Pyridoxal phosphate PLP, a derivative of vitamin B6. serves as the prosthetic group for Glycogen Phosphorylase. Pyridoxal phosphate PLP is held at the active site with the e-amino group of a lysine residue.
