Question

what would be the atp yield for a molecule that is catabolized to form one molecule of pyruvate in a eukaryotic cell? multiple choice 25 atp 12.5 atp 30 atp 10 atp 11.5 atp

Explanation:

In eukaryotic cells, during glycolysis, one glucose molecule is catabolized to two pyruvate molecules and yields a net of 2 ATP. So for the formation of one pyruvate molecule from glucose catabolism, the net ATP yield is 1 ATP directly from glycolysis - 2 ATP invested initially and 4 ATP produced, net 2 for 2 pyruvates, so 1 for 1 pyruvate. Additionally, during the conversion of glyceraldehyde - 3 - phosphate to 1,3 - bisphosphoglycerate, NADH is produced. When this NADH enters the electron - transport chain (ETC), considering the shuttle systems in eukaryotes (malate - aspartate shuttle or glycerol - 3 - phosphate shuttle), the NADH from glycolysis contributes to ATP production. The total ATP yield for the catabolism to form one pyruvate molecule is 10 ATP considering all the energy - generating steps including ETC contributions.

Answer:

10 ATP
