Answer is C. (Option c) Lactate dehydrogenase (pyruvate - lactate)is reversible. LDH conves lactate to pyruvate in liver pyruvate to lactate in muscle Pyruvate dehydrogenase - link reaction(irreversible)(Option b) 3 enzymes of glycolysis are irreversible Hexokinase/Glucokinase, Phosphofructokinase-1 Pyruvate kinase.
