What are the reactants of products in the electron transport chain for cellular respiration?

Electron succinate donor and nicotinamide adenine hydrochloride are the major biological reactants of the ETC (NADH).

These are produced via a process termed the cycle of citric acid (CAC).

Sugars and fats are divided into simple molecules like pyruvates, which subsequently enter the CAC.

Explanation:

Cellular respiration is described as the progressive enzymatic breakdown of glucose to produce energy, which in concert with ATP synthase, creates ATP.

The Cellular breathing method has 4 subdivisions; glycolysis, which disassembles glucose molecules to supply pyruvic acid molecules; a cancer cycle that further disassembles pyruvic acid with the aid of enzymes to provide four high energy substances, three of them NADH and one FADH2; The electron transportation chain in which electrons are conveyed and the energy released through a sequence of coenzymes and cytochromes; and lastly, the chemosmosis, where the energy emitted is utilized in transmitting protons from intermembrane space into a matrix with mitochondrial energy.
