Question

On each step in Electron Transport Sustem chain, a small charge is given off that will be used to synthesize ATP in the process of phosphorylation. When the electrons leave the chain, in pris, they combine with oxygen (final acceptor) to form water. During this process water is and why:
A) oxidized because electrons are lost which produces oxidized water
B) oxidized because electrons are gained which produces oxidized water
C) reduced because electrons are gained which produces reduced water
D) reduced, because electrons are lost which produces reduced water

Answer 1

Answer:

C) reduced because electrons are gained which produces reduced water

Explanation:

The electron transport chain (ETC) involves a series of chemical reaction based on the reduction and oxidation of molecules. According to the question, the electrons that leave the chain combine with a final electron acceptor called Oxygen. This reaction is a reduction reaction because oxygen gains electrons.

The gaining of electrons by Oxygen reduces it to water (H2O). Hence, water is said to be reduced because electrons are gained by oxygen to produce a reduced form, called water.
