Answer:
Breaking down of pyruvate occurs during the Krebs cycle
Step-by-step explanation:
Krebs cycle being the most important process of aerobic respiration. During kreb’ s cycle pyruvate is broken down to acetyl CoA which interacts with oxaloacetate to form the first metabolite of Krebs cycle known as citrate which contain 3 -COOH group That’s why kreb’ s cycle is also termed as Tricarboxylic acid cycle. The kreb’ s cycle happens in the mitochondrial matrix and generates a lot of chemical energy such as (ATP, NADH, FADH2) by the process of oxidation of the pyruvate and which is also measured as the end product of glycolysis.
