Question

The main organelle that helps in the modification and routing of newly synthesized proteins to their destination is:

• A. Mitochondria
• B. Endoplasmic reticulum
• C. Lysosome
• D. Chloroplast

Answer 1

The correct option is B

Endoplasmic reticulum

The correct option is B:

Explanation of the correct option:

1. The network of the tiny tubular structures scattered in the plane of cytoplasm is called the endoplasmic reticulum.
2. It is composed of three different structures: Cisternae, Tubules, and Vesicles

Functions of E.R:

1. Provides mechanical support
2. Helps in the transport of materials in the cytoplasm from one place to another.
3. The main organelle that helps in the modification and routing of newly synthesized proteins to their destination is the Endoplasmic Reticulum.

Explanation of the incorrect option:

Option A:

Mitochondria act as the site of aerobic respiration and help in ATP production.

Option C:

Lysosomes help in intracellular and extracellular digestion.

Option D:

Chloroplasts contain chlorophyll which is essential in trapping sunlight for photosynthesis.

Final answer: The main organelle that helps in the modification and routing of newly synthesized proteins to their destination is the Endoplasmic reticulum.
