Find out the correct sentence.a)Enzymes packed in lysosomes are made through RERb)Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectivelyc)Endoplasmic reticulum is related to the destruction of plasma membraned)Nucleoid is present inside the nucleoplasm of eukaryotic nucleusCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Option B: Rough endoplasmic reticulum produce proteins and smooth endoplasmic reticulum produce lipids. Hence, given statement is wrong.

Option C: 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.

Option D: 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.

Option A: 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)'

Answer

A

Answer

Enzymes packed in Lysosomes are made through RER (rough endoplasmic reticulum). Explanation: RER has ribosomes present on its surface which are responsible for the synthesis of proteins and enzymes are the proteins.

Answer

A)

Answer

Enzymes packed in lysosomes are made through RER

The correct sentence is option 'A': Enzymes packed in lysosomes are made through RER.

Explanation:

Rough Endoplasmic Reticulum (RER)
- The rough endoplasmic reticulum (RER) is a network of membrane-bound tubules and flattened sacs called cisternae.
- It is studded with ribosomes on its surface, giving it a rough appearance under a microscope.
- The RER is involved in the synthesis and processing of proteins that are destined to be secreted from the cell or inserted into membranes.
- Ribosomes on the surface of the RER synthesize proteins, which are then folded and modified within the RER cisternae.
- These proteins are then transported to their final destinations, such as the Golgi apparatus or the cell membrane.

Lysosomes
- Lysosomes are membrane-bound organelles found in animal cells.
- They contain a variety of enzymes that are involved in breaking down and recycling cellular waste materials.
- The enzymes packed inside lysosomes are synthesized within the cell and then transported to the lysosomes for packaging and activation.

Enzyme Synthesis
- Enzymes are proteins that catalyze specific chemical reactions in the cell.
- The synthesis of enzymes occurs within the cell's protein synthesis machinery, which includes the ribosomes.
- Ribosomes can be found both free in the cytoplasm and bound to the endoplasmic reticulum (ER).
- The ribosomes bound to the rough endoplasmic reticulum (RER) are involved in the synthesis of proteins that are destined for secretion or membrane insertion.
- These proteins, including enzymes, are synthesized by the ribosomes on the RER, and as they are synthesized, they are translocated into the RER cisternae.
- Within the RER, the proteins are folded and modified before being transported to their final destinations.

Lysosomal Enzymes
- Once the enzymes are synthesized and processed within the RER, they are transported to the Golgi apparatus.
- From the Golgi apparatus, they are packaged into vesicles called lysosomes.
- Lysosomes contain a low pH environment that activates the enzymes and allows them to carry out their functions of breaking down cellular waste materials.

Therefore, the correct sentence is option 'A': Enzymes packed in lysosomes are made through RER, as the RER is involved in the synthesis and processing of proteins, including enzymes, which are then transported to the lysosomes for packaging and activation.
