Question

Which of these is not related to the endoplasmic reticulum?

• A. It behaves as a transport channel for proteins between the nucleus.
• B. It transports materials between various regions in the cytoplasm.
• C. It can be the site of energy generation.
• D. It can be the site for some biochemical activities of the cell.

Answer 1

The correct option is C

It can be the site of energy generation.

The correct option is A.

Explanation of the correct option:

1. The endoplasmic reticulum is a collection of membrane tubules in the cytoplasm of a living cell.
2. It's connected to ribosomes and is in charge of producing lipids and proteins.
3. The endoplasmic reticulum is divided into several domains, each with its own purpose.
4. Energy is produced in Mitochondria. The endoplasmic reticulum isn't where it's made.

Explanation of the incorrect option:

Option B:

The nuclear envelope and the endoplasmic reticulum are linked. As a result, it works as a protein transporter between the nucleus and the cytoplasm.

Option C:

In contrast to molecules that float freely in the cytoplasm, the endoplasmic reticulum (ER) serves as a transport network for molecules that are targeted for specific modifications and destinations.

Option D:

The endoplasmic reticulum is a location for several biochemical activities as well as a transporter of protein and other materials.

Final answer:

It can be the site of energy generation is not related to the endoplasmic reticulum.
