Gated channels are especially important in regulating the transport of across a plasma membrane?
Professor55
Gated channels are important in transporting ion and other necessary molecules. Cells need to maintain a balance with their environment. If ions could freely diffuse through the plasma membrane, the right ionic environment required for cellular reactions is not met.
In the absence of the right ionic environment, many cellular reactions might stop. Therefore, there is a requirement for gates through which ions can travel into and out of the cell.
A typical example is the sodium-potassium channel. Here, the entry of three sodium ions is balanced out by the exit of 2 potassium ions. This is how the gate is designed.
Another example includes gates for the entry and exit of glucose molecules, a necessary nutrient for mammalian cells

What transport channels that are studded with ribosomes?
Rough ER are transport channels that are studded with ribosomes.
What is selective transport?
The transport of substances through membrane protein channels
All forms of passive transport depend on what?
Ion channels. Active transport depends on ATP. Passive transport does not depend on energy.
What transport protein allows ions to pass through the cell membrane?
Ion Channels allows ions to pass through the cell membrane.
What is an example of diffusion through ion channels?
Well, the materials pass through go in one end, and the ion channels open and let them pass through, but only with solutes
What transport channels that are studded with ribosomes?
Rough ER are transport channels that are studded with ribosomes.
What is lymph channels?
Lymph channels-- The vessels that transport lymph throughout the body. Lymph is a clear fluid that contains cells important in forming antibodies that fight infection.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
What is selective transport?
The transport of substances through membrane protein channels
What membrane of a cell acts like a channel?
The cell membrane contains various proteins that act as ion channels, allowing specific ions to pass through. These membrane channels are integral in regulating the transport of ions and maintaining the functionality of the cell.
What is the definition of selective transport?
selective transport is the transport of specific substances by means of protein channels and pumps.
Transport channels that are studded with ribosomes?
Rough ER
What are the different kind of cell transfort?
Active transport Passive transport (diffusion and transport using protein channels) Receptor mediated transport
All forms of passive transport depend on what?
Ion channels. Active transport depends on ATP. Passive transport does not depend on energy.
What protein group includes carriers and channels?
Transport Proteins
What is the role of protein channels in the membrane?
it transport baceria to the water
What forms channels for raw material transport in the cytoplasm?
Golgi
