Channel proteins take specific substances across cell membranes. Molecules passing through the membrane by channel protein is called mediated transport. To transport the substances, the channel protein must be embedded in the total cell membrane.
Protein channels.
There are generally channels which allow nutrients and other materials in or out of the cell. What goes in and out of the channel depends on the channel type.
One function of protein molecules in cell membranes is to transport molecules in and out of the cell. These proteins act as channels or carriers that help regulate the movement of substances across the membrane.

Protein channels.
Proteins such as ion channels embedded in the cell membrane function as gateways for specific ions to enter or exit the cell. These ion channels can be voltage-gated, ligand-gated, or mechanically-gated, regulating the flow of ions in response to changes in membrane potential, binding of specific molecules, or mechanical stimuli, respectively.
No, voltage-gated channels do not require ATP for their function.
The number of protein channels in a cell directly affects the rate of diffusion of molecules across the cell membrane. A higher number of protein channels allow for more molecules to pass through, leading to faster diffusion. Conversely, a lower number of protein channels may result in slower diffusion rates.
Protein channels that are sensitive to electricity are known as voltage-gated ion channels. These channels open and close in response to changes in the membrane potential, allowing specific ions to flow across the cell membrane and generate electrical signals.
