Question

In circumstances where the body requires prolonged or increased levels of a hormone, the DNA of target cells will specify the synthesis of more receptors on the surface of the cells of the target organ. This is known as ________.

Answer 1

Up-regulation.

Step-by-step explanation:

Hormones may be defined as the chemical messengers of the body that can transmit information and maintains homeostasis. The hormones can directly go into the bloodstream and may release through the special ducts.

The receptors of the hormone is required for the binding of the receptors. To maintain the normal homeostasis of the body, the body shows the up regulation and down regulation. In up regulation the hormone levels increases in the body by increasing the receptor on the specific target organ.

Thus, the correct answer is up regulation.
