The receptor that allows sodium into a cell is typically the sodium channel, specifically voltage-gated sodium channels. These channels open in response to changes in membrane potential, allowing sodium ions (Na+) to flow into the cell, which is crucial for generating action potentials in neurons and muscle cells. Additionally, ligand-gated sodium channels can open in response to the binding of specific neurotransmitters or other signaling molecules.

What receptor type is exemplified by opening a channel to let sodium into the cell?

The receptor type exemplified by opening a channel to let sodium into the cell is the ligand-gated ion channel. When a specific ligand, such as a neurotransmitter, binds to the receptor, it causes a conformational change that opens the channel, allowing sodium ions (Na+) to flow into the cell. This influx of sodium typically leads to depolarization of the cell membrane, which can trigger an action potential in neurons. Examples of such receptors include the nicotinic acetylcholine receptor and the glutamate receptor.


Which form of endocytosis involves a receptor?

Receptor-mediated endocytosis is the form of endocytosis that involves specific receptors on the cell membrane binding to ligands for internalization. This process allows for selective uptake of specific molecules into the cell.


What change does ACh cause in an ACh receptor?

Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.


Most receptor proteins are embedded in the?

Receptor proteins are embedded in the lipid bilayer of the cell membrane.


What is receptor mediated exocytosis of glucose?

Receptor-mediated exocytosis of glucose refers to the process where specialized receptors on the cell surface recognize glucose molecules and trigger the release of glucose-containing vesicles from within the cell to the outside environment. This mechanism allows cells to regulate the uptake and release of glucose in response to specific signals or conditions.

What is the receptor cell that detects the presence or absence of light and allows to see dim light?

The receptor cell that detects the presence or absence of light and allows us to see dim light is called a rod cell. Rod cells are responsible for low-light vision and are located in the retina of the eye.

The termination phase of cell signaling requires which of the following?

The termination phase of cell signaling often involves the removal of the signaling molecule from its receptor, deactivation of the receptor, and possibly degradation of the receptor-ligand complex to stop the signaling cascade. This allows the cell to return to its normal state and prevents prolonged or inappropriate signaling.

What structural feature on HIV allows it to attach to a receptor on the cell membrane of its target?

The surface of the HIV virion contains a glycoprotein called gp120 which allows it to attach to human immune system cells. The T cells of the immune systemhave a receptor on their cell membrane called CD45. A strong interaction between CD45 and gp120 has been shown.
