Mineral activator of enzyme aconitase is

Options

A. Mn
B. Mg
C. Fe
D. Cu.

Answer

To determine the mineral activator of the enzyme aconitase, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Enzyme**: The enzyme in question is aconitase. It plays a crucial role in metabolic pathways.

2. **Understand the Role of Aconitase**: Aconitase is involved in the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle, and the glyoxylate cycle. It catalyzes the conversion of citrate to isocitrate.

3. **Look for Mineral Activators**: The question asks for the mineral activator of aconitase. The options provided are magnesium, manganese, iron, and copper.

4. **Recall the Function of Iron**: In the context of the TCA cycle, iron is known to be a mineral that activates aconitase. It is essential for the enzyme's catalytic activity.

5. **Confirm the Conversion**: Aconitase catalyzes the conversion of citrate to isocitrate, and this reaction requires iron as a cofactor.

6. **Select the Correct Option**: Based on the information gathered, the mineral activator of the enzyme aconitase is iron. Therefore, the correct answer is option number 3, iron.

### Final Answer:
The mineral activator of the enzyme aconitase is **iron** (option number 3).
