This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Metabolism of carbohydrate, Subject name: Biochemistry
True about glycolysis are all except 
Select and explain. 
A. Provide nutrition to cancer cells, B. Substrate level phosphorylation at pyruvate kinase, C. Two carbon end product is formed, D. NADPH is formed by glyceraldhyde-3-phosphate dehydrogenase
C: Two carbon end product is formed
Answer: C: Two carbon end product is formed 
Explanation: Glycolysis is the breakdown of glucose to pyruvic acid under aerobic conditions and to lactic acid under anaerobic conditions (a 3 carbon compounds)In fast-growing cancer cells, glycolysis proceeds at a high rate, forming large amounts of pyruvate, which is reduced to lactate and expoed.Glyceraldehyde-3-phosphate dehydrogenase form NADHSubstrate-level phosphorylation at Phosphoglycerate kinase, Pyruvate kinaseRef: Harper 27e, page no: 169
