Question

What are some of the CELLULAR FUNCTIONS that a cell membrane participates in?

Answer 1

1. Selective permeability: The cell membrane acts as a barrier, allowing certain molecules to enter and exit the cell while preventing others from passing through.

2. Signal transduction: The cell membrane is involved in the transmission of signals from outside the cell to the inside, allowing the cell to respond to its environment.

3. Cell-cell recognition: The cell membrane contains proteins that allow cells to recognize each other and interact with one another.

4. Endocytosis and exocytosis: The cell membrane is involved in the process of endocytosis, which is the uptake of molecules from outside the cell, and exocytosis, which is the release of molecules from inside the cell.

5. Cell adhesion: The cell membrane contains proteins that allow cells to adhere to one another and form tissues.

Answer 2

There are two main functions

Step-by-step explanation:

First, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
