Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.

What is a cell that produces a signal molecule?
A cell that produces a signal molecule is known as a signaling cell or secreting cell. These cells release signaling molecules, such as hormones or neurotransmitters, which can travel to target cells to initiate a response.
What is the difference between Target cells and non-target cells?
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
What is the difference between an endocrine cell and a target cell?
the endocrine cell has a jelly like substance and so so it drops off it in the blood vessel and so target cells make hormones in the blood vessel to bind into thereceptor on a target cell sometimes a target cell is very close or far away
Target cells are equipped with specific receptor molecules?
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
What is the difference between a hormone and a secondary messenger?
The primary effector creates a signal that can diffuse within the cell. This signal is called the "secondary messenger." (The neurotransmitter is the first messenger.) The secondary messenger may then activate a "secondary effector" whose effects depend on the particular secondary messenger system.
What recognizes signal molecules such as growth factors and hormones?
receptors
Do hormones target molecules that originate outside the body?
no, pheromones do though.
What is a cell that produces a signal molecule?
A cell that produces a signal molecule is known as a signaling cell or secreting cell. These cells release signaling molecules, such as hormones or neurotransmitters, which can travel to target cells to initiate a response.
What is the difference between Target cells and non-target cells?
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
What system releases signal molecules into the bloodstream?
endocrine glands.
What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
What is the chemical signal carried through the blood?
The chemical signal carried through the blood is primarily hormones. Hormones are produced by glands in the body and travel through the bloodstream to target specific cells or organs to regulate various physiological functions.
What is the difference between an endocrine cell and a target cell?
the endocrine cell has a jelly like substance and so so it drops off it in the blood vessel and so target cells make hormones in the blood vessel to bind into thereceptor on a target cell sometimes a target cell is very close or far away
Hormones can do all of the following to a target cell except make the cell?
Hormones can influence target cells by altering their function, stimulating growth, and triggering cellular responses. However, hormones do not create or form the cells themselves; that process is governed by cellular division and differentiation. Instead, hormones act as signaling molecules that regulate existing cellular activities.
Target cells are equipped with specific receptor molecules?
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
How do target organs most often regulate the pituitary gland?
Target organs regulate the pituitary gland through a feedback loop involving hormones. When a target organ senses a change in hormone levels, it can release specific hormones to signal the pituitary gland to either increase or decrease its production of certain hormones. This feedback mechanism helps maintain homeostasis in the body.
What is the difference between a hormone and a secondary messenger?
The primary effector creates a signal that can diffuse within the cell. This signal is called the "secondary messenger." (The neurotransmitter is the first messenger.) The secondary messenger may then activate a "secondary effector" whose effects depend on the particular secondary messenger system.
