the figure below represents an overview of the different entry pathways to cellular respiration when different macromolecules are digested for energy production. why are none of the digestive products entering the electron transport chain directly?



Answer :

None of the digestive products enter the electron transport chain directly as only electrons carried by reduced electron carrier molecules like NADH are accepted by the electron transport chain.

The system's electron donor is NADH. By providing electrons to NADH dehydrogenase, it starts the electron transport cycle (blue). NADH dehydrogenase receives two electrons from NADH. The complex additionally moves two protons into the intermembrane space at the same time from the mitochondria's matrix region.

What is the mechanism of the electron chain?

The ETC is made up of a group of proteins that are affixed to the inner mitochondrial membrane and organic molecules that allow electrons to pass through and release energy through a series of redox processes. The protein ATP-synthase uses chemiosmosis to create a significant amount of ATP using the energy released to create a proton gradient.
