Question

find out the correct statement ​

Answer 1

Answer:

Among the following, Statement (a) is the correct one.

Explanation:

• The undefined nuclear region in the cytoplasm of prokaryotic cells e.g., bacteria devoid of a nuclear membrane is called the nucleoid.

• The prokaryotic cells consist of a single chromosome, which is the direct content of the cytoplasm, there is no nuclear envelope that separates the nucleus from the cytoplasm.

• The nuclear envelope contains many pores (the nuclear pores) and encloses the liquid ground substance, the nucleoplasm. Within nucleoplasm, two types of nuclear structures are embedded-the nucleolus and chromatin material.

• Rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER) produce proteins and lipids respectively.

• The endoplasmic reticulum (ER) is involved in forming the plasma membrane along with some other organelles (biogenesis of membranes).

• RER has ribosomes present on its surface which are responsible for the synthesis of proteins and enzymes in the proteins. The rough endoplasmic reticulum has no role in the production of lipids.

Hence option a) is the correct statement.

Answer 2

Complete 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:

Enzymes packed in Lysosomes are made through RER (rough endoplasmic reticulum) is the correct answer

Explanation:

• Ribosomes, which are found on the surface of RER, are in charge of the creation of proteins, which are made up of enzymes.
• There is no function for the rough endoplasmic reticulum in the synthesis of lipids. Similarly, the breakdown of the plasma membrane is unrelated to the endoplasmic reticulum.
• In prokaryotes, the nucleoid is an unidentified nuclear region.

Rough endoplasmic reticulum (RER):

• Rough endoplasmic reticulum (RER), an organelle with a continuous membrane that is a network of linked flattened sacs found in the cytoplasm of eukaryotic cells and is crucial for protein synthesis
• The well-known milk proteins casein and whey proteins are among the proteins produced by the rough ER.
• Before merging with the plasma membrane and releasing their contents into the milk ducts, these proteins are bundled into secretory vesicles or giant micelles and transported through the Golgi network.
