Body cells that react to particular hormone are called?
target cells
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.
One of the major transmembrane proteins in a “tight junction” is?
One of the major transmembrane proteins in a tight junction is occludin. It plays a key role in sealing the intercellular space between adjacent cells to maintain the integrity and selective permeability of the epithelial or endothelial barrier.
Where do glands send messages to target cells?
Glands send messages in the form of hormones to target cells through the bloodstream. Hormones are released by glands into the blood where they travel to target cells throughout the body to elicit a specific response. Target cells have specific receptors that recognize and respond to the hormones.
How can cells regulate the diffusion of molecules through protein channels?
Cells can regulate the diffusion of molecules through protein channels by controlling the opening and closing of these channels. This regulation can be achieved through various mechanisms, such as changes in the cell's membrane potential or the binding of specific molecules to the channel proteins. By adjusting the activity of these channels, cells can selectively allow certain molecules to pass through while blocking others.
What is the transmembrane protein channels that are specialized for the passage of water?
The transmembrane protein channels that are specialized for the passage of water is aquaporin's. Osmosis is the diffusion of water down its concentration gradient.

What is the main cellular target of the HIV virus which causes AIDS?
Helper T cells
What is the cellular abnormality that causes cystic fibrosis?
abnormal chloride channels that trap salt inside cells lining the lung passageways.
What cells are affected by cystic fibrosis?
The protein affected by cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator or CFTR. CFTR acts as a channel that transports negatively charged chloride ions into and out of cells. This helps control the flow of water in tissues. CFTR also regulates the function of other channels that transport positive sodium ions into and out of cells.
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 Peripheral cells sensitive to the presence of hormones are called?
Target Cells
What do scientists currently believe is the cause of Cystic Fibrosis How are the faulty gene inherited and what direct effect does that have on the affected cells?
The faulty gene causes the misfolding of a protein called the Cystic Fibrosis Transmembrane conductance Regulator (CFTR). CFTR is responsible for the movement of chloride and sodium ions into and out of cells. The lack of salt and water on the surface of the cells causes the mucus to become extremely thick and sticky which builds up in and clogs organs.
What causes the rapid change in the resting membranes potential that initiates an action potential?
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
What tissue is responsible for transporting carbohydrates from leaves to other parts of the plant?
For tissue that is found in the leaves, transmembrane protein is responsible for transporting carbohydrates from leaves to various parts of the plant . Sugars are taken up by the transmembrane protein with the help of companion cells.
One of the major transmembrane proteins in a “tight junction” is?
One of the major transmembrane proteins in a tight junction is occludin. It plays a key role in sealing the intercellular space between adjacent cells to maintain the integrity and selective permeability of the epithelial or endothelial barrier.
Do most cells have sodium channels?
Yes, most cells have sodium channels. These channels play a crucial role in regulating the movement of sodium ions into and out of cells, which is essential for processes such as nerve signaling, muscle contraction, and maintaining cell volume.
