Question
The citric acid cycle involves the formation of ______________________.
- Lactic acid from glucose
- Pyruvic acid conversion to energy transformation
- Pyruvic acid from glucose
- ATP from ADP
Hint:
Pyruvic acid conversion to energy transformation
The correct answer is: Pyruvic acid conversion to energy transformation
Glycolysis produces 2 pyruvate molecules. The pyruvate molecules then forms acetyl CoA and one molecule of carbon dioxide is released. The acetyl-CoA molecules then enters the citric acid cycle. The end product of citric acid cycle is 2 carbon dioxide molecules, 1 GTP, 3 NADH and 1 FADH2.
