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 else can I help you with?
Is there another name for carrier proteins?
Yes, carrier proteins are also known as carrier molecules or transport proteins. They facilitate the movement of molecules across cell membranes by binding to specific substances and transporting them across the cell.
What substances are too large for carrier proteins?
Large molecules such as proteins and polysaccharides are usually too large to be transported by carrier proteins. These molecules are often transported through other mechanisms like endocytosis or exocytosis.
What role do membrane transport proteins, such as channels, carrier proteins, and pumps, play in the movement of substances across cell membranes?
Membrane transport proteins, like channels, carrier proteins, and pumps, help regulate the movement of substances across cell membranes. Channels allow specific molecules to pass through, carrier proteins transport molecules across the membrane, and pumps use energy to move molecules against their concentration gradient. These proteins are essential for maintaining the balance of substances inside and outside the cell.
What functions do carrier proteins perform in active transport?
Carrier proteins in active transport actively pump molecules or ions against their concentration gradient across a cell membrane using energy from ATP. They allow specific substances to be moved across the membrane in a controlled manner, helping to maintain cellular homeostasis and regulate cell function.
What controls which substances can move in and out of a cell?
The phospholipid bilayer of the cell membrane controls the movement of substances in and out of the cell. It is selectively permeable, allowing some molecules to pass through while restricting others based on factors such as size, charge, and solubility. Additionally, proteins such as channel proteins and carrier proteins aid in the transport of specific substances across the membrane.
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.
Is there another name for carrier proteins?
Yes, carrier proteins are also known as carrier molecules or transport proteins. They facilitate the movement of molecules across cell membranes by binding to specific substances and transporting them across the cell.
Which mmolecules help control movement of substances through cell mmembrans?
Carrier proteins or transport proteins.
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.
Are carrier proteins specific in their action?
Yes, carrier proteins are specific in their action. They selectively bind and transport only certain molecules or ions across a cell membrane or within a cell, based on their shape and properties. This specificity allows cells to regulate the movement of substances in and out of the cell with a high degree of control.
What kind of protein helps some substances cross the cell membrane?
Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.
