Pyruvate can be conveed directly into all the following except :
Phosphoenol pyruvate
Alanine
Acetyl CoA
Lactate
A i.e. Phosphoenol PyruvatePyruvate can be directly conveed to acetyl CoA (by oxidative decarboxylation), oxaloacetate (by carboxylation), alanine (transamination); and lactate (in anaerobic conditions). But pyruvate can not be directly conveed to phosphoenol pyruvate (a reaction of gluconeogenesis)Q. However, phosphoenol pyruvate can be directly conveed to pyruvate (in glycolysis)Q.
