Question

Find out the correct sentence.

• A. Enzymes packed in lysosomes are made through RER (rough endoplasmic reticulum)
• B. Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectively
• C. The endoplasmic reticulum is related to the destruction of the 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 RER (rough endoplasmic reticulum)

The correct option is A

An explanation for the correct option:

1. RER is a rough endoplasmic reticulum
2. It has ribosomes present on its surface which help in the synthesis of proteins
3. Proteins are formed by translation from mRNA.
4. Enzymes are proteins.
5. Act as biological catalysts.

Explanations for the incorrect option:

Option B

1. The endoplasmic reticulum is a network of tubule-like structures spread in the cytoplasm
2. The rough endoplasmic reticulum has ribosomes on its surface.
3. If ribosomes are absent they appear smooth and are called the smooth endoplasmic reticulum.
4. The rough endoplasmic reticulum was seen in the cells actively participating in protein synthesis and secretion.
5. The formation of lipids takes place in the smooth endoplasmic reticulum.
6. In animal cells, steroidal hormones are formed in the smooth endoplasmic reticulum.

Option C

1. The cell membrane is largely composed of lipids and proteins.
2. Phospholipids are present in the cell membrane in the bilayer
3. Enzyme phospholipases help in breaking down membrane phospholipid
   

Option D

1. A nucleoid in a prokaryotic cell contains genetic material.
2. Eukaryotic cells contain a nucleus.
3. Nucleoplasm is the matrix of the nucleus.
   

Final answer: Enzymes packed in lysosomes are made through the rough endoplasmic reticulum is the correct sentence.
