Select the correct matching in the following pairs:

Options

A. Smooth ER-Synthesis of lipids
B. Rough ER - Synthesis of glycoge
C. Rough ER- Oxidation of fatty acids
D. Smooth ER - Oxidation of Phospholipids

Answer

To solve the question regarding the correct matching of the pairs related to the functions of the smooth and rough endoplasmic reticulum, follow these steps:

### Step-by-Step Solution:

1. **Understand the Functions of Smooth Endoplasmic Reticulum (SER)**:
- The SER is primarily involved in the synthesis of lipids, including phospholipids and cholesterol.
- It plays a role in the detoxification of drugs and poisons.
- It is also involved in carbohydrate metabolism and the storage of calcium ions.

2. **Understand the Functions of Rough Endoplasmic Reticulum (RER)**:
- The RER is studded with ribosomes, which are the sites of protein synthesis.
- Its main function is to produce and process proteins that are either secreted from the cell, incorporated into the cell's plasma membrane, or sent to an organelle.

3. **Evaluate the Given Pairs**:
- Pair 1: Smooth Endoplasmic Reticulum - Synthesis of Lipids: **True** (This is a correct function of SER).
- Pair 2: Rough Endoplasmic Reticulum - Synthesis of Glycogen: **False** (RER is not primarily involved in glycogen synthesis; this is mainly a function of the liver).
- Pair 3: Smooth Endoplasmic Reticulum - Oxidation of Fatty Acids: **True** (SER is involved in fatty acid oxidation).
- Pair 4: Smooth Endoplasmic Reticulum - Oxidation of Phospholipids: **False** (While SER is involved in lipid metabolism, oxidation of phospholipids is not a primary function).

4. **Identify the Correct Matches**:
- From the evaluation, the correct matches are:
- Smooth Endoplasmic Reticulum - Synthesis of Lipids (True)
- Smooth Endoplasmic Reticulum - Oxidation of Fatty Acids (True)

5. **Conclusion**:
- The correct pairs are 1 and 3. Therefore, the answer to the question is that there are two correct pairs: 1 and 3.
