Which of the following best describes a hormone a chemical messenger?

Which of the following best describes a hormone a chemical messenger?

Terms in this set (45) which of the following best describes a hormone? a chemical messenger transported by the bloodstream that stimulates target cells in another organ often a good distance away.

What do you call to a chemical messenger in the body?

The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.

What are chemical messenger that transfer information?

Hormones are chemical messengers that transfer information and instructions from one set of cells to another. 5. Once a hormone is secreted, it travels from the endocrine gland that produced it through the bloodstream to the cells designed to receive its message.

What best describes a hormone?

Hormones are chemical substances that act like messenger molecules in the body. After being made in one part of the body, they travel to other parts of the body where they help control how cells and organs do their work. For example, insulin is a hormone that’s made by the beta cells in the pancreas.

Which of the following best describes a hormone chegg?

Which of the following best describes a hormone? Chemical messengers that diffuse from their point of origin locally to affect other cells physiology.

What is the name of chemical messengers that transfer information and instructions from one set of cells to another?

As the body’s chemical messengers, hormones transfer information and instructions from one set of cells to another.

What is the chemical messenger of the nervous system?

neurotransmitter, also called chemical transmitter or chemical messenger, any of a group of chemical agents released by neurons (nerve cells) to stimulate neighbouring neurons or muscle or gland cells, thus allowing impulses to be passed from one cell to the next throughout the nervous system.

How are chemical messengers used in indirect communication?

Indirect Communication via Chemical Messengers Most cells communicate by secreting a chemical (ligand) that reversibly binds to a receptor on a target cell. The binding of the ligand to the receptor produces a response in the cell by mechanisms called signal transduction.

How are chemical messengers classified by their structure?

Chemical messengers can be classified by their chemical characteristics including their solubility in water and chemical structure. Hydrophobic (lipophilic) – Molecules are lipid soluble and can easily cross the plasma membrane. Hydrophilic (lipophobic) – Molecules that are water soluble and do not readily cross the plasma membrane.

How are cells different in their receptors for chemical messengers?

Cells vary in the receptors they have and a single target cell may have receptors for different chemical messengers. For example, skeletal muscle has receptors for both acetylcholine which causes contraction and insulin which stimulates glucose intake and metabolism. Receptor Binding and Target Cell Response

Why are chemical messages not sent to different parts of the body?

C. Chemical messages could not be sent to different parts of the body because the phospholipid bilayer forms hormones. D. A person would be vulnerable to disease because the phospholipid bilayer helps to fight infections in the body. THIS SET IS OFTEN IN FOLDERS WITH…
