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 solve the question regarding the minerals useful in photosynthesis and binding of ribosomal subunits, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Role of Minerals in Photosynthesis**:
- Photosynthesis is a process that requires certain minerals for its proper functioning. One of the key minerals involved in this process is manganese (Mn).
- Manganese is a micronutrient that plays a crucial role in the splitting of water molecules during photosynthesis, which is essential for the release of oxygen.

2. **Identify the Role of Minerals in Binding of Ribosomal Subunits**:
- Ribosomes are essential for protein synthesis in cells, and certain minerals are required for the proper functioning of ribosomes.
- Magnesium (Mg) is the mineral that is necessary for the binding of ribosomal subunits. It helps stabilize the ribosomal structure during protein synthesis.

3. **Summarize the Findings**:
- From the above analysis, we conclude that:
- The mineral useful in photosynthesis is manganese (Mn).
- The mineral necessary for the binding of ribosomal subunits is magnesium (Mg).

4. **Final Answer**:
- Therefore, the minerals useful in photosynthesis and binding of ribosomal subunits are respectively manganese (Mn) and magnesium (Mg).
