What is a membrane protein that allows specific charged molecules to pass through from one side of the membrane to another?
A membrane protein that permits the passage of specific substances is selectively permeable. They allow the solvent as specific solutes to pass through.
What are openings in the cell membrane called?
Protein channels
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
How does a plasma membrane determine selectivity of molecules?
Plasma membrane possesses specific protein channels and lipid bilayer. Protein channels are of million different types, each allow a specific molecule to pass through it regarding its size, shape, charges on it, solubility, etc. Fat soluble molecules pass through lipid bilayer.

What are the special structures in the cell membrane that allow water and sugar pass through it made of?
These special structures are called protein gates or protein channels. Water is able to diffuse through the cell membrane since it is a small molecule. However, there are channels called aquaporins that allow water to enter the cell. A glucose molecule cannot just diffuse into a cell. There are glucose channels on the surface of the cell membrane that bind glucose molecules and allow them to enter the cell.
What structures in the cell membrane function as ion channels?
protein channels

What is the role of protein channels in the membrane?
it transport baceria to the water

What is the role of protein channelsin the cell membrane?
Protein channels allow the cell membrane to transfer large molecules across it. Remember, diffusion only occurs with small molecules. Protein channels are a necessity to transfer larger molecules.
What is selective transport?
The transport of substances through membrane protein channels
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
