What part of the cell is like a gate?
In this analogy, the cell membrane is like a wall, keeping what's in the cell inside, and what is outside of the cell out. However, there are "gates" called receptors. Receptors are large protein molecules embedded in the membrane, with one end outside and one end inside. Different gates, or receptors, permit certain things to enter. For example a glucose receptor lets glucose enter the cell. When a glucose molecule passes a glucose receptor, the glucose molecule is attracted to the receptor by an electric charge. It then binds to the receptor, but now the balance of the charges in the protein molecule has been changed, so the protein molecule changes shape. When it changes shape, it pulls the glucose into the cell and then lets go of the glucose. Now the protein is free to return to its original shape, and the glucose is inside the cell.
What channel can help move things across the membrane?
Protein channels help move particles across the cell membrane
Give example of facilitated diffusion?
Glucose molecule going through the protein channel to enter and exit the cell. Hope I could help.
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.
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 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.
What is a molecule used by glucose as a piggyback into and out of the cell in the process of active transport?
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
