B. glycoproteins

C. plasma proteins

D. peripheral proteins

​

Answer 1

Explanation:

I think the answer will be

B. glycoproteins

Answer 2

C. Plasma proteins are NOT part of the plasma membrane of a cell.

The plasma membrane of a cell:

• The phospholipid bilayer in the fluid mosaic model has embedded peripheral and integrated proteins.
• Peripheral proteins are located at the edges of the lipid layers, while integrated proteins are found on the inside and extend across the bilayer.
• Hydrophilic phosphate heads and hydrophobic phosphate tails make up this bilayer.
• Hydrophobic Proteins are found embedded in membranes.
• The carbohydrate chains in the glycoproteins are pointed away from the membrane's inner surface.
• The plasma membrane is a mosaic of elements, primarily phospholipids, cholesterol, and proteins, that move fluidly and freely in the plane of the membrane, according to the fluid mosaic model.
