Question

pyruvate starts with 3 carbon atoms but is converted to acetyl-coa, which has 2 carbon atoms. that missing carbon atom is lost in a molecule of : A. Oxaloacetate B. NADH C. ATP D. FADH2

Answer 1

Step-by-step explanation:

Two pyruvate molecules remain at the end of glycolysis and are still very rich in energy that can be extracted. Although no ATP is directly produced during pyruvate oxidation, it is the next stage in the process of converting the residual energy into ATP

This process happens in the matrix, the mitochondria's deepest chamber, in eukaryotes. It takes place in the cytoplasm of prokaryotes. Overall, pyruvate oxidation transforms the three-carbon molecule into the two-carbon molecule acetyl CoA CoAstart text, C, o, A, end text, which is attached to Coenzyme A. This results in a NADH NADHstart text, N, A, D, H, end text and the release of one carbon dioxide molecule. In the subsequent step of cellular respiration, acetyl CoA CoAstart text, C, o, A, end text serves as fuel for the citric acid cycle.
