Question

what is the name of the step where pyruvate is converted into acetyl coa?
substrate level phosphorylation
citric acid cycle
electron transport chain
glycolysis

Explanation:

Pyruvate is converted to Acetyl - CoA in a step called pyruvate decarboxylation or pyruvate oxidation which occurs before the citric acid cycle. Substrate - level phosphorylation is a way of generating ATP. The citric acid cycle uses Acetyl - CoA as a starting point. The electron - transport chain is involved in oxidative phosphorylation. Glycolysis is the process that produces pyruvate. None of the given options are correct, but the closest related process is the transition step to the citric acid cycle where pyruvate is converted to Acetyl - CoA.

Answer:

None of the above options are correct. The correct step is pyruvate oxidation (or pyruvate decarboxylation) which is the transition step before the citric acid cycle.
