The α-ketoglutarate dehydrogenase complex closely resembles the large enzyme complex that converts pyruvate to acetyl CoA, the pyruvate dehydrogenase complex.

The conversion of pyruvate to Acetyl CoA is the decarboxylation process.（）

The first step of conversion of pyruvate into acetyl CoA is oxidation.（）

Mammals cannot use acetyl-CoA as a precursor of glucose, because the ________________________ is irreversible and cells have no other pathway to convert acetyl-CoA to pyruvate.

The conversion of pyruvate to Acetyl CoA is the rate limiting step acetyl CoA synthesis.（）

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 final product of the EMP pathway, in addition to ATP and reducing power, has only 2 pyruvate molecules.

The amino acids belonging to the pyruvate family includes: A: alanine B: valine C: lysine D: leucine

The final product of the EMP pathway, in addition to ATP and reducing power, has only 2 pyruvate molecules. A: 正确 B: 错误

The important substance for the special flavor of beef is ( ) in beef. A: Benzoic acid B: pyruvate C: fatty acid D: amino acid
