Voltage-gated channels are proteins in the cell membrane which open when stimulated by a voltage (an electrical signal). The voltage causes the channel to open, thereby allowing the entry or exit of whatever substance the channel relates to.

An example of this the the voltage-gated sodium channels on neurons. When an action potential (a voltage), passes over the cell, it open these channels and allows sodium to enter the cell.

How do voltage sensitive channel proteins respond to electrical signals?

Voltage-sensitive channel proteins respond to changes in membrane potential by undergoing conformational changes that open or close the channel. When the membrane potential reaches a specific threshold, the channel opens, allowing ions to flow across the membrane. This allows for the generation and propagation of electrical signals in the form of action potentials.


Is the flexible nature of a cell membrane result from its channel proteins?

Yes it is


Is the flexible nature of a cell membrane results from its channel proteins true?

Yes, the flexible nature of a cell membrane results from its phospholipid bilayer, which allows for movement and bending. Channel proteins, on the other hand, facilitate the transport of specific molecules across the membrane but do not contribute significantly to the overall flexibility of the membrane.


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.


Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?

A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.


Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?

Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
