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.
举一反三
- Which one of the following is a condition decreased the oxidation of acetyl CoA by the citric acid cycle?
- Acetyl CoA can be finally oxidized to CO2 and H2O via citric acid cycle.
- The conversion of pyruvate to Acetyl CoA is the rate limiting step acetyl CoA synthesis.（）
- The conversion of pyruvate to Acetyl CoA is the decarboxylation process.（）
- The first step of conversion of pyruvate into acetyl CoA is oxidation.（）
