WebFeb 18, 2024 · These data suggest that when demand for NAD + to support oxidation reactions exceeds the rate of ATP turnover in cells, NAD + regeneration by mitochondrial respiration becomes constrained, promoting fermentation, despite available oxygen. This argues that cells engage in aerobic glycolysis when the demand for NAD + is in excess … WebFigure 7.8 The first half of glycolysis uses two ATP molecules in the phosphorylation of glucose, which is then split into two three-carbon molecules. Second Half of Glycolysis (Energy-Releasing Steps) So far, glycolysis has cost the cell two ATP molecules and produced two small, three-carbon sugar molecules.
WebMay 9, 2024 · By considering the glucose released by the action of debranching enzyme, there is a yield of 30 molecules of ATP, because two molecules of ATP are used in the preparatory phase of glycolysis. The cost-gain rate is 2/30, namely, there is an energy yield of about 93,3%. WebThe glycolytic part (one glucose → 2 pyruvates → 2 lactate) of the Cori cycle produces only 2 ATP per molecule of glucose. The gluconeogenesis to resynthesize a glucose (2 lactate → 2 pyruvates → one glucose) consumes 2 GTP and 4 ATP, which is equal to 6 ATP. The net cost is 6-2 = 4 ATP.
