Question

What is the function of proteins and carbohydrates that are embedded in a cell membrane?

Answer 1

Transmembrane protein channels and transporters: Transmembrane proteins extend through the lipid bilayer of the membranes; they function on both sides of the membrane to transport molecules across it. Nutrients, such as sugars or amino acids, must enter the cell, and certain products of metabolism must leave the cell.

Answer 2

The functions of proteins and carbohydrates that are embedded in cell membrane include the following functions:

• They control what enters the cells and what leaves the cells. This means that these proteins and carbohydrates ensure that the cell receives only the right nutrients.

• The proteins and carbohydrates act as storage molecules for water.

• The reproduction process of the cell is managed and directed by the proteins and carbohydrates embedded in the cell membrane.
