Question

How do the membranes of eukaryotic cells vary?

1) Some proteins are unique to each membrane.
2) Some membranes are not selectively permeable.
3) Some membranes have unique molecules that have yet to be characterized.
4) None of these.

Answer 1

Eukaryotic cell membranes vary in terms of protein composition, permeability, and the presence of unique molecules.

Step-by-step explanation:

Eukaryotic cells have a variety of membranes, including the plasma membrane and organelle membranes. These membranes differ in several ways:

1. Some proteins are unique to each membrane. Different membranes contain different proteins that carry out specific functions.
2. Some membranes are not selectively permeable. While most membranes in eukaryotic cells are selectively permeable, there are some membranes that allow the passage of all substances.
3. Some membranes have unique molecules that have yet to be characterized. There are still molecules in certain membranes that have not been fully identified or characterized.

In summary, the membranes of eukaryotic cells vary in terms of protein composition, permeability, and the presence of unique molecules.
