Question

Mechanical support, enzyme circulation protein synthesis, and detoxification of drugs are the function of

• A. ER
• B. Ribosomes
• C. Dictyosomes
• D. Chloroplast

Answer 1

The correct option is A

ER

The correct option is A:

Explanation of the correct option:

1. ER stands for Endoplasmic reticulum.
2. It provides mechanical support to the cell, by maintaining its shape.
3. Rough ER contains ribosomes on its surface, which synthesizes protein.
4. Smooth ER helps in the detoxification of drugs as well.

Explanation of the incorrect option:

Option B:

Ribosomes are responsible to synthesize proteins only.

Option C:

Dictyosomes polymerizes sugar into polysaccharide and modifies proteins from ER.

Option D:

Chloroplasts contain chlorophyll which is important for photosynthesis to take place.

Final answer: Mechanical support, enzyme circulation protein synthesis, and detoxification of drugs are the function of ER.
