First one is Model and second one is Inference
The answer is B because it makes the most logical sense and the rest of the answered are obviously incorrect, it’s screaming “I’m wrong!!!”
Isocitrate + NAD+ -> a-ketoglutarate + CO2 + H2
The amount of ATP produced from one molecule of glucose will decrease because NADH is no longer produced in the isocitrate dehydrogenase reaction. Without generation of this high energy electron carrier there will be less electrons from one molecule of glucose that are transferred to and through the electron transport chain. So there will be less protons (H+ ions) pumped into the intermembrane space. So there will be less of a H+ ion gradient across the inner mitochondrial membrane to drive the synthesis of ATP by ATP synthase.
