Homework Answers
the preparatory reaction is the conversion of pyruvate to acetyl CoA by the pyruvate dehydrogenase, during this reaction NAD+ is reduced to NADH and this reaction occurs in the mitochondrial matrix.
so the answer is
NAD+ goes to NADH+ H+ as acetyl CoA forms.
( this is hthe reaction whcih connetc glycolyss ot TCA cycle the producet of glycolysis is converted to acetyl CoA which is used in the TCA cycle)

In glycolysis, one glucose molecule yields pyruvates, ATP and NADH. Depending on the system used to shuttle the electrons from NADH into mitochondria, these NADH become NADH or FADH2. Converting the pyruvate(s) into acetyl-CoA's produces 2 NADH. One pyruvate/Two pyruvates pass(es) through the citric acid cycle starting with acetyl-CoA produces GTP, FADH2, and NADH. In the electron transport chain, each FADH2 generates ATP and each NADH ATP.
