Question

Find out the correct sentence

• A. Enzymes packed in lysosomes are made through Rough Endoplasmic Reticulum.
• B. Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectively.
• C. Endoplasmic reticulum is related to the destruction of plasma membrane.
• D. Nucleoid is present inside the nucleoplasm of the eukaryotic nucleus.

Answer 1

The correct option is A

Enzymes packed in lysosomes are made through Rough Endoplasmic Reticulum.

The correct option is A.

Explanation for correct option:

1. The rough endoplasmic reticulum contains ribosomes on its surface which are responsible for synthesizing proteins and enzymes.
2. The RER is thus responsible for the synthesis of lysosomal enzymes.

Explanation for incorrect options:

Option B:

1. The RER is responsible for protein synthesis and packaging.
2. Most of the function occurs in the membrane-bound ribosomes.
3. The SER is not involved in protein synthesis but it is involved in the synthesis of lipids and steroids.

Option C:

1. The endoplasmic reticulum is involved in synthesizing, folding, and transporting proteins.

Option D:

1. Nucleoid is an irregularly shaped section present in the prokaryotic cells where the DNA is stored.
2. It also contains RNA, proteins, and enzymes.

Final answer: The correct sentence is enzymes packed in lysosomes are made through Rough Endoplasmic Reticulum.
