Which one of the following is the terminal electron acceptor?

Select the correct option for the chemiosmotic hypothesis.

What is produced by oxidative phosphorylation?

Given below are two statements.
$Statement-I$: During aerobic respiration, $ETS$ releases energy in a stepwise manner to prevent damage to cells.
$Statement-II$: During aerobic respiration, $ETS$ provides water molecules.
In the light of the above statements, choose the correct answer from the options given below.

In oxidative phosphorylation,oxidation and phosphorylation take place simultaneously and form
