Question

Apart from transportation, what is the other major functions of membrane bound proteins?

Answer 1

Transport proteins move molecules and ions across the membrane.

Explanation:

Membrane proteins help organisms survive by performing a range of tasks: Signals are relayed between the cell's internal and exterior environments through membrane receptor proteins. Molecules and ions are transported across the membrane by transport proteins.

Membrane proteins have a major function.

Membrane proteins let cells interact, maintain their structure, carry out changes induced by chemical messengers, and transport and transfer material, among other things.

The roles of a cell membrane

• A Physical Obstacle.
• Selective Permeability is a term used to describe the ability of a material
• Exocytosis and Endocytosis are two different types of endocytosis.
• Signaling between cells.
• Phospholipids.
• Proteins.

Answer 2

MEMBRANE-BOUND PROTIENS -

• Protein molecules are integrated into the membrane cell.
• The proteins are of two types namely Integral and peripheral membrane-bound proteins.
• The major functions of Membrane-bound proteins are -

1. Cell adhesion - Helps to stick cells with other cell surfaces.

2. Enzymatic activity - Proteins sometimes act as an enzyme with active sites to facilitate the metabolic pathways.

3. Structural function - Maintains cell shape and provides a point of attachment for the cytoskeleton and extracellular fluid.

4. Signal transduction - Binding site for chemical messengers.

5. Cell recognition - Identification of the cells to build the immune system.

6. Intercellular junction - Facilitates communication between two or more cells for transfer of materials.
