Question
What are the functions of the cell membrane?Multiple select question.It is the site of signal transduction.It is the site of protein synthesis.It is a selectively permeable barrier.
Solution
The functions of the cell membrane include:
-
It is the site of signal transduction: The cell membrane contains receptors that bind to signal molecules and initiate a series of events within the cell. This process is known as signal transduction.
-
It is a selectively permeable barrier: The cell membrane controls the movement of substances in and out of the cell. It allows some substances to pass through while preventing others, hence it is selectively permeable.
However, the cell membrane is not the site of protein synthesis. Protein synthesis occurs in the ribosomes, which are either free in the cytoplasm or attached to the endoplasmic reticulum.
