C. The shape of a protein allows it to perform several different jobs.
First, the electron
transport chain transfer the electrons from electron donors to electron
acceptors using both reduction and oxidation reactions.
Next, the energy
released in these reactions is captured as an electrochemical proton gradient
that triggers the synthesis of ATP synthase and produce adenosine triphosphate
(ATP) from ADP and phosphate group in the process called chemiosmosis.
Lastly, ATP stores
energy chemically in the form of highly strained bonds and together, the
electron transport chain and chemiosmosis makes up the oxidative
phosphorylation which is found in the inner mitochondrial membrane.

Answer:
Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.
Explanation:
When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.
On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.
Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.
Mitosis allows organisms to generate genetic diversity.
