Answer:
The correct answer is option C. up-regulation.
Explanation:
When the body requires the increased level of the hormone, target cells increase the synthesis of more receptors on the cell surface of the target organ. This process is known as the up-regulation of the receptors for the hormone.
Up-regulation is an increase in the receptors present on the cell surface of target cells so that cells can easily bind to the hormone. Up-regulation makes the cells increase the sensitivity to a hormone.
Thus, the correct answer is option C up-regulation.

Which part of the human body controls the nervous system?
Brain
Explanation:
Nervous system is made up of the brain and the spinal cord, as the brain controls everything
During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)
