The question is incomplete as it does not have the options which are:
A) creatine phosphate.
B) glycolysis.
C) substrate phosphorylation.
D) oxidative phosphorylation.
E) de novo synthesis.
Answer:
D) oxidative phosphorylation.
Explanation:
The ATP is the energy molecule which provides energy to every metabolic process in the organism.
The ATP in humans is produced by a process called cellular respiration where the last phase of the process called electron transport chain produces the highest amount of protein. The electron transport chain is also known as the oxidative phosphorylation as the oxygen is gained and electrons are lost during the phase.
Thus, D) oxidative phosphorylation is correct.
