Final answer:
Oxidation of succinate through Complex II results in the synthesis of approximately 2 ATP molecules, as it is linked to the production of FADH2 which generates fewer ATPs than NADH.
Step-by-step explanation:
When succinate is oxidized through complex 2 in the electron transport chain (ETC), the product is one molecule of FADH2. The oxidation of one FADH2 molecule through the ETC leads to the synthesis of approximately 2 ATP molecules. This is because electrons transferred from FADH2 enter the ETC at a lower energy level compared to NADH, resulting in a smaller proton gradient for ATP production through oxidative phosphorylation.
