Minerals involved in carbohydrate translocation, maintaining ribosome structure and activation of nitrogenase respectively are

Options

A. Mn,B,Ca
B. Ca,Mg,Mo
C. B,Mg,Mo
D. Cu,Mg,B

Answer

To solve the question regarding the minerals involved in carbohydrate translocation, maintaining ribosome structure, and activation of nitrogenase, we can follow these steps:

### Step 1: Identify the mineral for carbohydrate translocation
- Carbohydrate translocation in plants is primarily facilitated by **boron**. Boron plays a crucial role in the movement of sugars and other carbohydrates within the plant.

**Hint:** Think about which mineral is essential for the movement of sugars in plants.

### Step 2: Identify the mineral for maintaining ribosome structure
- The structure of ribosomes is maintained by **magnesium**. Magnesium ions are essential for stabilizing the ribosomal RNA and the overall structure of ribosomes.

**Hint:** Consider which mineral is commonly associated with ribosomes and their structural integrity.

### Step 3: Identify the mineral for activation of nitrogenase
- The enzyme nitrogenase, which is crucial for nitrogen fixation, requires **molybdenum** as a cofactor for its activity. Molybdenum is essential for the proper functioning of nitrogenase.

**Hint:** Recall which mineral is known to be a cofactor for enzymes involved in nitrogen fixation.

### Step 4: Combine the identified minerals
- From the above steps, we have identified:
- Carbohydrate translocation: **Boron**
- Ribosome structure maintenance: **Magnesium**
- Activation of nitrogenase: **Molybdenum**

### Step 5: Match with the options provided
- The correct sequence of minerals (Boron, Magnesium, Molybdenum) matches with option 3.

**Final Answer:** The minerals involved in carbohydrate translocation, maintaining ribosome structure, and activation of nitrogenase respectively are **Boron, Magnesium, and Molybdenum**.
