What helps the plasma membrane function?

Question

nuclei and endoplasmic reticula
chloroplasts and mitochondria
channels and chain-like structures
pumps and gelatin-like material

Answer 1

The plasma membrane's function is primarily assisted by channels and chain-like structures.

1. Channels: These are integral membrane proteins that form pores allowing specific molecules to pass in and out of the cell. They are essential for transport tasks such as selective permeability, which contributes to maintaining the cell's internal environment.

2. Chain-like structures: This may refer to the lipid bilayer composition of the plasma membrane, which consists of phospholipids arranged in a double layer with long hydrophobic tails. This structure provides fluidity and flexibility, allowing the membrane to perform its functions effectively.

While pumps and the gelatin-like material (cytosol) also play roles in maintaining cellular functions, channels and the structural characteristics of the membrane are more directly related to the membrane's transport and communication functions.
