Krebs's cycle

Acetyl CoA (2C) combines with oxaloacetate(4C) to form citrate (6C) CoA returns back to the link reaction to be used again and citrate is decarboxylated into a 5C compound dehydrogenation of citrate also occurs and NADH is made ATP is also produced the 5C compound is then converted back into oxaloacetate by decarboxylation dehydrogenation occurs again to form FADH2 and 2NADH molecules this reaction also happens twice per glucose molecule
