"WebPyruvic acid is decarboxylated and the 2 H ions are picked up by NAD+ and thus it provides two mole of NADH for each mole of glucose (net = 6 ATP produced). This enzymatic step needs coenzyme A and its activity is highly regulated by the concentration of acetyl CoA, ATP, and NADH. Through PDH, one mole of glucose produces 2 NADH or 6 … " - How is pyruvate acid with the kreb cycle

How is pyruvate acid with the kreb cycle

WebThe Krebs cycle is the second stage of cellular respiration. During the Krebs cycle, energy stored in pyruvate is transferred to NADH and FADH2, and some ATP is produced. Once citrate has formed, the citrate then goes on to step 2 in which it is transformed into an isomer molecule called isocitrate.
