What else can I help you with?
What are openings in the cell membrane called?
Protein channels
What is the organelle that regulates what enters or exits the cell is called?
its the cell membrane - not to be confused with the cell wall
Ion channel that are always open are called?
Ion channels that are always open are called leak channels. They allow a continuous flow of ions across the cell membrane, helping to maintain the resting membrane potential of the cell.
Passages that permit a cell membrane to be permeable as needed are called?
Passages that permit a cell membrane to be permeable as needed are called ion channels. These channels allow ions such as sodium, potassium, and calcium to flow in and out of the cell, regulating the cell's electrical and chemical properties.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
What is a system of membrane channels?
In the nervous system the system of membrane channels is called the neuroreceptors. Neurotransmitters use the neuroreceptors as binding sites.
What are openings in the cell membrane called?
Protein channels
What are water channels in the membrane of a cell called?
aquaporin i think

Ion channel that are always open are called?
Ion channels that are always open are called leak channels. They allow a continuous flow of ions across the cell membrane, helping to maintain the resting membrane potential of the cell.
What are other names for a pore in a cell membrane?
Depends on what the pore does. If they are channels - they are called Channels. Voltage gated / ligand activated channels. If they are to communicate with neighbouring cells - they are called gap junctions.
What is the system of membrane bound channels located throughout the cytoplasm in a eukaryotic cell?
the endoplasmic reticulum
When the membrane bound cavities of the endoplasmic reticulum or channels or sac like they are called?
Cisternae
In the membrane of a cell channels serve as what?
Channels in the cell membrane serve as passageways for the selective transport of ions and molecules into and out of the cell. They help maintain the cell's internal environment by controlling the flow of substances across the membrane.
A series of membrane-enclosed channels studded with ribosomes is called the?
rough endoplasmic reticulum
Passages that permit a cell membrane to be permeable as needed are called?
Passages that permit a cell membrane to be permeable as needed are called ion channels. These channels allow ions such as sodium, potassium, and calcium to flow in and out of the cell, regulating the cell's electrical and chemical properties.
Channels within the structure of the cell membrane are composed of....?
Simply stated: ProteinsChannels within the structure of the cell membrane are composed of proteins. A protein that forms an ion channel through a membrane is called a transmembrane protein.
