The Impact of Adrenaline Hormone on Cells

The Role of Adrenaline Hormone

Adrenaline, also known as epinephrine, is a hormone and neurotransmitter produced by the adrenal glands in response to stress, fear, or excitement. It plays a crucial role in the body's fight-or-flight response, increasing heart rate, dilating airways, and mobilizing energy reserves to prepare the body for action.

Adrenaline's Target Cells

According to the data provided, the hormone adrenaline can affect only cells with appropriately shaped receptors. This means that adrenaline will bind only to cells that have specific receptors on their surface that are compatible with adrenaline molecules.

Explanation:

-Hormones are chemical messengers that move throughout the body coordinating complex biological processes such as growth, fertility, and metabolism.

-While all cells are exposed to hormones circulating in the bloodstream, not all cells react. Only a hormone's target cells, which have receptors for that hormone, will respond to its signal.

-When adrenaline binds to its receptor on a target cell, it triggers a series of biochemical reactions within the cell that ultimately lead to the cell's response to the hormone's signal.

Therefore, the correct answer to the question is 1. appropriately shaped receptors.

The hormone adrenaline can affect only cells with

  1. appropriately shaped receptors
  2. the appropriate antibodies
  3. Ribosomes that produce adrenaline
  4. genes that break down adrenaline
What is the correct answer?

The correct answer is 1. appropriately shaped receptors.
