Question

Which of these material is not a component of plasmamembrane
lipids B.carbohydrates
C Protien. D. DNA​

Answer 1

Answer:

The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

Answer 2

D. DNA​ is not a component of the plasma membrane.

Plasma membrane:

• A biological membrane known as the cell membrane shields and isolates the interior of every cell from its external environment.
• The membrane that separates a cell's interior from its surroundings is found in every cell and is referred to as the plasma membrane or cell membrane.
• Bacterial and plant cells' plasma membranes are connected by a cell wall.

Structure of plasma membrane:

• Like all other cellular membranes, the plasma membrane is composed of both lipids and proteins.
• The membrane's primary structural component is a phospholipid bilayer, which creates an impermeable barrier between two aqueous compartments.
• All cells have the cell membrane, sometimes referred to as the plasma membrane, which serves as a barrier between the interior of the cell and the outside world.
• Semipermeable lipid bilayers make up the cell membrane.
• The cell membrane regulates how materials enter and leave the cell.
