(ATP, FADH2, NADH + H+, CO2 are all products) For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. 3 molecules of NADH; 1 molecule of FADH 2; 1 molecule of GTP; A molecule of glucose contains 2 pyruvate molecules, so 1 glucose molecule will produce double the amount of products listed above as it moves through the Krebs cycle. Management. As you will see later in this tutorial, it is the free energy from these redox reactions that is used to drive the production of ATP. 1 Answer. However, in the heart and liver, the malate-aspartate shuttle occurs, resulting in 2.5 ATP per NADH. Starting with one molecule of glucose, the energy-containing products of glycolysis are _____. vanessaveverett vanessaveverett CO2, ATP, NADH, FADH2. In addition to ATP, what are the end products of glycolysis? Multiply that by the amount of ATP per NADH or FADH2 to yield: 10 NADH X 2.5 ATP/NADH = 25 ATP 2 FADH2 X 1.5 ATP/FADH2 = 3 ATP. Main Difference – NADH vs NADPH. This reaction releases acetyl-CoA, FADH2 and NADH, the three of which then enter another metabolic process called citric acid cycle or Krebs cycle, in which ATP is produced to be used as energy. Basically, respiration is how we convert food into energy using water and oxygen. Site of Reaction : Mitochondrial matrix in Eukaryotes NADH and pyruvate. The malate—aspartate shuttle is sensitive to the NADH/NAD+ ratios in the cytosol and mitochondria, and cannot operate if the mitochondrial NADH/NAD+ ratio is higher than that in the cytosol. FAD/FADH2 differ from NAD+/NADH since they are bound tightly (Kd approx 10-7 - 10-11 M) to enyzmes which use them. In addition to ATP, what are the end products of glycolysis?
