Question

In cellular respiration, where do the high-energy electrons that move through the electron transport chain originate? water NADH and FADH2 NAD+ and FAD glucose

Answer 1

ANSWER:

In cellular respiration, high energy electrons which moves through an electron transport chain originates in glucose.

EXPLANATION:

These are moved through the transport chain by NAD+ and FAD which eventually become NADH and FADH2. Cellular respiration is a complex process that takes place in all cells of organisms.  

The process converts the biochemical energy from the nutrients into 'ATP' and then eventually into waste products that are removed from the body. Cellular respiration is the metabolic pathway which breaks glucose to produce ATP that provides energy to the cells and organisms.
