1) Carrier protein ONLY transport the non-polar substance such as glucose,except water,because water particles could slide through phospholipid bilayer across plasma membrane from the area of high concentration to the area of lower concentration.
2) Substance which pass through phospholipid bilayer bind at specific sites.
3) Carrier protein will change its shape appropriately to the shape of the substance passing through plasma membrane.

What substances are too large for carrier proteins?
Glucose...It's a HUGE molecule that is broken down into Glycogen for storage.
What functions do carrier proteins perform in active transport?
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
How does a carrier protein work?
Carrier proteins facilitates the transport of specific substances through intracellular compartments or across the cell membrane. They bond and then drag the molecules across the bilipid layer, releasing them on the opposite side.
What Carrier Proteins Transport Glucose Into A Muscle Cell?
carrier proteins transport glucose into a muscle cell
What controls which substances can move in and out of a cell?
The cell membrane regulates the movement of substances in and out of the cell.How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.
What part of the cell is considered the cell door?
You could be referring to the cell membrane or carrier proteins. Both allow certain substances to enter cells.

Which mmolecules help control movement of substances through cell mmembrans?
Carrier proteins or transport proteins.
What functions do carrier proteins perform in active transport?
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
How do carrier proteins transport substances across membranes?
They control what enters and exits the cell :)
What substances enter and leave the cells?
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
What substances enter the cell by attachment to a passive transport protein carrier?
Phospholipids
In active transport carrier proteins do what?
They help transfer substances from the outside of the cell membrane to the inside.
Facilitated diffusion carrier proteins and cell membrane pumps both?
They both transport substances up their concentration gradients.
How does a carrier protein work?
Carrier proteins facilitates the transport of specific substances through intracellular compartments or across the cell membrane. They bond and then drag the molecules across the bilipid layer, releasing them on the opposite side.
What Carrier Proteins Transport Glucose Into A Muscle Cell?
carrier proteins transport glucose into a muscle cell
In order for substances to move through the cell membrane what must there be?
For passive diffusion, a concentration gradient which uses pore proteins. For active diffusion, carrier proteins and energy are required.
