Identifying the Incorrect Statement Regarding the Electron Transport Chain
During cellular respiration, the process of oxidative phosphorylation plays a critical role in the production of ATP. The electron transport chain consists of several protein complexes located in the inner mitochondrial membrane. Each complex has distinct roles in the transfer of electrons originating from NADH and FADH2. Consider the following statements regarding the electron transport chain and its function in bioenergetics:
1. Complex I transfers electrons from NADH to ubiquinone and contributes to proton pumping.
2. Complex II, unlike Complex I, does not contribute to proton pumping but does facilitate electron transfer from succinate.
3. The final electron acceptor in the chain is glucose.
4. The electrochemical gradient created by proton pumping drives ATP synthesis via ATP synthase.
Based on the descriptions of the electron transport chain, which of the following statements is NOT true?
