Answer:
The correct answer is option e) "All of these are correct".
Step-by-step explanation:
The production of ATP via the electron transport chain is a complex pathway that follows multiple steps and multiple proteins. These steps include: the creation of a steep electrochemical gradient that activates ATP synthase, as well as the generation of a H ion gradient across the inner mitochondrial membrane, which drives ATP synthesis during oxidative phosphorylation by electrons binding to NADH and FADH2.
