During electron transport system (ETS) electron transport proceeds from carries that have ________redox potential to those having_____redox potential. This electront transport down the energy gradient leads to the formation of ATP from ADP and Pi, which is referred to as___________.

Options

A. low, high, oxidative phosphorylation
B. low, high, oxidative decarboxylation
C. high, low, oxidative phosphorylation
D. high, low, oxidative decarboxylation

Answer

a

Explanation

Many intermediate cytochromes and other carriers having their intermediate redox potentials are arranged in a series which transport electrons from NADH of `FADH_(2)` to `O_(2)`. This sequence of electron carriers constitutes the electron transport system (ETS). The electron transport to those having high redox potential. The electron transport down the energy gradient through electron transport system leads to the formation of ATP from ADP and inorganic phosphate. This generation of ATP is called as oxidative phosphorylation.
