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. Endoplasmic reticulum is related with the destruction of plasma membrane.
• D. Nucleoid is present inside the nucleoplasm of eukaryotic nucleus.

Answer 1

The correct option is A Enzymes packed in lysosomes are made through RER (rough endoplasmic reticulum).

Rough endoplasmic reticulum produce proteins and smooth endoplasmic reticulum produce lipids. Hence, given statement is wrong.
Endoplasmic reticulum is related with the making of plasma membrane. It makes the proteins (with the help of ribosomes) and lipids which are used for membrane synthesis. Hence, given statement is false.
Nuclear material of a prokaryotic cell consists of a single chromosome which is not membrane bound and lies naked in cytoplasm. Such, nuclear region of cytoplasm is called as nucleoid. Hence, given statement is wrong.
Lysosomal enzymes are made by rough endoplasmic reticulum. The ribosomes present on rough endoplasmic reticulum are involved in protein synthesis. Almost all enzymes are proteins

So, the correct answer is 'Enzymes packed in lysosomes are made through RER (rough endoplasmic reticulum)'
