Question

Quizplus · Accepted Answer

The removal of a carbon (as CO₂) from a molecule of pyruvate results in the formation of acetyl CoA, which enters the citric acid cycle (also known as the Krebs cycle) to complete the oxidation of glucose. Lactate is formed during anaerobic respiration, glyceraldehyde-3-phosphate is produced during glycolysis, oxaloacetate is a key intermediate in the citric acid cycle, and citrate is the first intermediate formed in the citric acid cycle.
