Where do you think a glucagon hormone most likely binds to send it's signal to the cell?
In the plasma membrane of target cells (P - apex)
What else can I help you with?
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.
Suppose a hormone is released by an endocrine gland The hormone is carried by the bloodstream to its target cells When it reaches the cells the hormone binds to receptors on the cells' surfaces?
Once the hormone binds to the receptors on the cells' surfaces, it triggers a specific cellular response or signal transduction pathway within the target cells. This response may involve changes in gene expression, enzyme activation, or other cellular functions that help regulate various physiological processes in the body. The binding of the hormone to the receptor is a key step in the communication between the endocrine system and the target cells.
When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
When a signal molecule binds to a receptor protein on the cell membrane, it triggers a cascade of signaling events inside the cell through intracellular signaling molecules like second messengers. These second messengers relay the signal from the receptor at the cell membrane to the cell's interior, which initiates a response by activating various cellular processes. This signal transduction pathway enables the inside of the cell to detect and respond to the binding of the signal molecule at the membrane.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
What are target cells for releasing hormones in?
in the hypothalamus is what my book says:) .............from what I have read the releasing hormones originate in the hypothalamus, but the target cells are found in the anterior pituitary gland.
What kind of hormone is glucagon?
Glucagon is released when blood sugar levels drop too low. It stimulates the liver to convert glycogen to glucose, therefore increasing blood sugar levels. It is a hormone agonist (i.e. binds to a receptor in a cell and triggers a response).Its opposing hormone is insulin, an antagonist which is release when blood sugar levels climb too high.
Region of the chromatin that binds a given hormone?
The region of the chromatin that binds a given hormone is typically the hormone response element (HRE). HREs are specific DNA sequences that are recognized and bound by hormone receptors. When a hormone binds to its HRE, it can activate or repress gene expression, leading to specific cellular changes or responses.
What hormone requires a G-protein?
G-protein coupled receptors (GPCRs) are the largest family of cell surface receptors, they mediate a response to a huge variety of signalling molecules (eg. hormones). A few examples of hormones that use GPCRs are; adrenalin, prostaglandins and glucagon.
How is hormone specificity achieved?
each hormone receptor only binds to one hormone
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
What recognize a hormone's chemical structure?
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
What type of protein binds with a hormone to send a message to a cell?
a receptor
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.
What makes cells multiply?
Cells are told to divide through a complex signal pathway. A signal in the blood (I think it's a hormone) binds to a protein on the cell's surface, which triggers a 9 step process of protein messengers which eventually reaches the nucleus and tells it to start mitosis.
Which hormone is water soluble and therefore binds extracellular receptors?
Insulin and epinephrine
What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
What recognizes a hormone's chemical structure in the endocrine system?
Hormone receptors on cell membranes recognize a hormone's chemical structure in the endocrine system. When the hormone binds to the receptor, a cell changes its behavior.
