Minerals useful in photosynthesis and binding of ribosomal subunits are respectively:

Options

A. S,Mg
B. K,B
C. Mn,Mg
D. Fe,Mo

Answer

To answer the question regarding the minerals useful in photosynthesis and the binding of ribosomal subunits, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Role of Minerals in Photosynthesis**:
- Photosynthesis is a process that converts light energy into chemical energy in plants. Certain minerals play crucial roles in this process.

2. **Determine the Specific Mineral for Photosynthesis**:
- The mineral that is particularly important for photosynthesis is **manganese (Mn)**.
- Manganese is involved in the splitting of water molecules during the light-dependent reactions of photosynthesis, which is essential for the release of oxygen.

3. **Identify the Role of Minerals in Ribosomal Subunit Binding**:
- Ribosomes are cellular structures that synthesize proteins. They consist of ribosomal RNA and proteins, and their assembly requires certain minerals.

4. **Determine the Specific Mineral for Ribosomal Subunit Binding**:
- The mineral that is essential for the binding of ribosomal subunits is **magnesium (Mg)**.
- Magnesium acts as a cofactor that stabilizes the structure of ribosomes and is crucial for protein synthesis.

5. **Summarize the Findings**:
- The minerals useful in photosynthesis and binding of ribosomal subunits are respectively **manganese (Mn)** and **magnesium (Mg)**.

### Final Answer:
- The minerals useful in photosynthesis and binding of ribosomal subunits are respectively: **Manganese (Mn)** and **Magnesium (Mg)**.
