Question

During pyruvate decarboxylation reaction, pyruvate is converted to _______________ compound, through a reaction called ______________ .

Answer

Pyruvate decarboxylation is an oxidative decarboxylation reaction, or an oxidation reaction where a carboxylate group is removed. This reaction converts pyruvate which was produced through glycolysis to acetyl CoA to be used in the Citric Acid Cycle.

Compare your answer with the correct one above

Question

Which enzyme complex catalyzes the pyruvate decarboxylation reaction?

Answer

The pyruvate dehydrogenase complex is an enzyme complex that consists of 3 enzymes, which work together to catalyze the pyruvate decarboxylation reaction, where pyruvate is converted to acetyl CoA.

Compare your answer with the correct one above

Question

Where does the pyruvate decarboxylation reaction occur?

Answer

Pyruvate decarboxylation occurs in the mitochondrial matrix. The acetyl CoA produced from the pyruvate decarboxylation reaction will undergo the Citric Acid cycle also in the mitochondrial matrix.

Question

For each glucose molecule that undergoes glycolysis, how many acetyl CoA molecules are produced at the end of pyruvate decarboxylation?

Answer

During glycolysis, for each molecule of glucose, two molecules of pyruvate are produced ( glucose+ NAD+ + 2 ADP + 2Pi-> 2 pyruvate+ 2 ATP + 2NADH+. These 2 molecules of pyruvate then undergo the pyruvate decarboxylation reaction: 2(pyruvate+ CoA-SH+ NAD+ -> NADH+ CO2+ acetyl CoA).

Compare your answer with the correct one above

Question

Which is not a product of pyruvate decarboxylation reaction?

Answer

The pyruvate decarboxylation reaction is pyruvate+ CoA-SH+ NAD+ -> NADH+ CO2+ acetyl CoA.

Question

During the pyruvate decarboxylation reaction, acetyl CoA is produced through which type of bond linking an acetyl group to coenzyme A?

Answer

During the pyruvate decarboxylation reaction , a thioester bond links the acetyl group of pyruvate with coenzyme A to produce acetyl CoA.
