Question

Which of the following are NOT considered as the part of endomembrane system?

1. Mitochondria
2. Endoplasmic reticulum
3. Chloroplasts
4. Golgi complex
5. Peroxisomes

Choose the most appropriate answer from the options given below:

• A. A, C and E only
• B. A and D only
• C. A, D and E only
• D. B and D only

Answer 1

Answer: (A)

A, C and E only

Answer 2

(A) Mitochondria are not considered part of the endomembrane system. They are double-membrane organelles involved in energy production through cellular respiration.
(C) Chloroplasts are not part of the endomembrane system. They are organelles found in plant cells that are responsible for photosynthesis.
(E) Peroxisomes are not part of the endomembrane system. They are single-membrane organelles involved in various metabolic processes, including the breakdown of fatty acids and detoxification.

Endoplasmic Reticulum (B) and Golgi complex (D) are indeed part of the endomembrane system, involved in protein synthesis, modification, and transport within the cell.

The correct option is (A): A, C and E only
