- The human erythrocyte loses its nucleus and mitochondria during differentiation. It therefore relies on _________ alone for its supply of ATP. The lactate produced by glycolysis returns to the liver, where gluconeogenesis converts it to glucose, to be stored as glycogen or recirculated to peripheral tissues. The erythrocyte has constant access to glucose in the bloodstream.
- Under normal conditions, the rates of glycolysis and of the citric acid cycle are integrated so that only as much glucose is metabolized to pyruvate as is needed to supply the citric acid cycle with its fuel, the acetyl groups of acetyl-CoA. Pyruvate, lactate, and acetyl-CoA are normally maintained at steady-state concentrations.
- The acetyl CoA required for the synthesis of fatty acids is derive from ( ). A: fat mobilization B: β-oxidation of fatty acids C: degradation of amino acids D: glycolysis E: degradation of glucoses
- The carbon dioxide is primary a product of A: Krebs cycle B: Glycolysis C: Electron transport phosphorylation D: Lactate fermentation E: Fatty acid synthesis
- During long term starvation, the energy in brain mainly come from A: glucose oxidation B: ketone bodies oxidation C: lactate oxidation D: amino acid oxidation E: fatty acid oxidation
