Which process is NOT a metabolic fate for pyruvate in liver tissue?

a) transamination to alanine

b) carboxylation to oxaloacetate

c) reduction to lactate

d) oxidative decarboxylation to acetyl-CoA

e) phosphorylation to phosphoenolpyruvate

e) phosphorylation to phosphoenolpyruvate

Explanation:

phosphoenol pyruvate is not the fate of the pyruvate. pyruvate can convert into the phosphoenole pyruvate in the reverse of the glycolysis which will utilize the ATP. So, this can not be the fate of pyruvate because in the breakdown of the glucose through glycolysis pyruvate is the end product and phosphoenol pyruvate is the intermediate.
