What are the molecules in a plasma membrane that provide basic membrane structure cell identity and membrane fluidity?
Phospholipids are the main molecules in the plasma membrane that provide basic membrane structure. Glycolipids and glycoproteins contribute to cell identity through their unique carbohydrate chains. Cholesterol helps to maintain membrane fluidity by modulating the packing of phospholipids.
Plasma membrane in eukaryotic cells is made up of?
The plasma membrane in eukaryotic cells is primarily composed of a phospholipid bilayer. This bilayer contains embedded proteins that help regulate the movement of molecules in and out of the cell. Additionally, cholesterol molecules are also present in the plasma membrane to provide stability and fluidity.
Do Hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily?
Yes, hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily due to their similar hydrophobic nature. The nonpolar tails of the phospholipids in the membrane provide a favorable environment for hydrophobic molecules to move across.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins

Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.

What Molecules in the plasma membrane function as transporters?
Proteins
What are most of the molecules that compose the plasma membrane?
phospholipids

phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
What polymers provides protection in the plasma membrane?
Phospholipids are the main polymers that provide protection in the plasma membrane. They form a lipid bilayer that acts as a barrier to protect the cell from the external environment. Additionally, cholesterol molecules help maintain the stability and fluidity of the membrane.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion
What is the job of the plasma membrane?
it regulates the entry and exitof the molecules
The cell membrane also is called the?
The cell membrane is also known as the plasma membrane or the cytoplasmic membrane. It is a biological membrane that separates all cells' interior from the outside, though can be permeated by selection ions and molecules. Its basic function is to protect the cell from its surroundings.
