Question

The endoplasmic reticulum (ER) consists of two distinct regions known as smooth ER and rough ER. Classify each statement about structure and function as characteristics of smooth ER, rough ER, or both

(a) It's surface that faces the cytoplasm lacks ribosomes
(b) it's surface that faces the cytoplasm is studded with ribosomes
(c) It is part of the endoembrane system
(d) it functions in detoxification of drugs
(e) a major function is the manufacture of proteins
(f) a major function is lipid synthesis

Answer 1

Answer:

Endoplamic reticulum

It is part of the endoembrane system

Rough endoplasmic reticulum

1. It's surface that faces the cytoplasm is studded with ribosomes

2. a major function is the manufacture of proteins

Smooth endoplasmic reticulum

1. It's surface that faces the cytoplasm lacks ribosomes

2.  it functions in detoxification of drugs

3. a major function is lipid synthesis

Explanation:

The endoplasmic reticulum is the membranous fattened sac-like structure present attached to the nuclear membrane in the cytoplasm.

The endoplasmic reticulum is considered a part of the endomembrane system of the cell and if of two types:

1. Rough ER: characterized by the rough surface due to the presence of ribosomes attached to the ER. The ribosomes are the sits of the proteins synthesis therefore RER is involved in the synthesis of proteins.

2. Smooth endoplasmic reticulum: characterized by the smooth surface as it does not have the ribosomes and is involved in the synthesis of lipid biomolecules and detoxification of the drugs.

Answer 2

Classifying each statement about structure and function as characteristics of smooth ER, rough ER, or both:

Rough endoplasmic reticulum

1. It's surface that faces the cytoplasm is studded with ribosomes
2. a major function is the manufacture of proteins

Smooth endoplasmic reticulum

1. It's surface that faces the cytoplasm lacks ribosomes
2. it functions in detoxification of drugs
3. a major function is lipid synthesis

The endoplasmic reticulum

is the membranous fattened sac-like structure present attached to the nuclear membrane in the cytoplasms. It is of two types:

Rough ER:

• characterized by the rough surface due to the presence of ribosomes attached to the ER.
• The ribosomes are the sites of the proteins synthesis
• RER is involved in the synthesis of proteins.

Smooth endoplasmic reticulum

• characterized by the smooth surface as it does not have ribosomes
• is involved in the synthesis of lipid biomolecules
• detoxification of the drugs.
