      2. How does the actual ATP yield compare to the theoretical yield? The theoretical yield is 36 ATP, but some protons leak across the inner mitochondrial membrane, and energy is used to move pyruvate and ADP into the mitochondrion. These losses reduce the …

      If oxygen is present, pyruvate enters the mitochondrion where enzymes of the citric acid cycle complete the oxidation of the organic fuel to carbon dioxide. After pyruvate enters the mitochondrion via active transport, it is converted to a compound called acetyl coenzyme A or acetyl CoA.

      Because the pyruvate does not enter the citric acid cycle (aka Krebs cycle), there is still a lot of energy which is not removed from the fuel. Under aerobic respiration, a molecule of glucose yields 36-38 ATP, but the same molecule of glucose yields only 2 ATP under …

      2 Molecules of Pyruvate made _____ Reduced NAD produced. The rest of aerobic respiration occurs in the mitochondria. The Link Reaction. Pyruvate still contains a lot of chemical potential energy. The link reaction is a stage linking glycolysis and Krebs cycle. It actively transports the pyruvate into the matrix of the mitochondria.

      If oxygen is present, pyruvate enters the mitochondrion where enzymes of the Krebs cycle complete the oxidation of the organic fuel to carbon dioxide. As pyruvate enters the mitochondrion, a multienzyme complex modifies pyruvate to acetyl CoA which enters the Krebs cycle in the matrix. A carboxyl group is removed as CO2.
