Question

1. where can a cholesterol be found within the cell membrane? 9. what is the purpose of the proteins that are found in the cells membrane? 10. what are carbohydrates used for within the cell membrane?

Explanation:

1. Cholesterol is embedded in the lipid - bilayer of the cell membrane, interspersed among the phospholipids.
2. Membrane proteins have functions like transport (facilitating movement of substances across the membrane), cell - cell recognition, signal transduction (relaying signals into the cell), and enzymatic activity.
3. Carbohydrates in the cell membrane are mainly used for cell - cell recognition and also play a role in cell adhesion.

Answer:

1. Embedded in the lipid - bilayer, interspersed among phospholipids.
2. Transport, cell - cell recognition, signal transduction, enzymatic activity.
3. Cell - cell recognition and cell adhesion.
