question:
Question: Pyruvate dehydrogenase (PDH): 
 Options:  <0> It catalyzes the reversible transformation of pyruvate into acetyl-CoA and vice versa. <1> It catalyzes the irreversible carboxylation of pyruvate into citrate, and with it, its entry into the citric acid cycle. <2> It connects the degradation of carbohydrates, with the synthesis of acetyl-CoA and its entry into the citric acid cycle. <3> It allows the use of acetyl-CoA derived from the degradation of fatty acids for the synthesis of glucose. <4> It is activated in the presence of high concentrations of acetyl-CoA and NADH + H +.
