Which type of membrane is most abundant within a cell?
A. ER membrane
C. Plasma membrane
B. Golgi membrane
D. Nuclear membrane



Answer :

Final answer:

The plasma membrane is the most abundant type of membrane within a cell and is crucial for regulating cellular processes.


Explanation:

Plasma membrane is the most abundant type of membrane within a cell. It is a fluid phospholipid bilayer embedded with proteins and glycoproteins that regulates what enters and exits the cell.

The endoplasmic reticulum (ER) is responsible for manufacturing most of the cell's membranes, including the plasma membrane. The ER consists of two types: rough ER (RER), which has ribosomes on its surface, and smooth ER (SER), which lacks ribosomes.

The ER membrane, being continuous with the nuclear envelope, contributes significantly to the total membrane content in eukaryotic cells.
