What is the mineral activator involved in transition reaction of aerobic respiration ?

Options

A. Cu^2+`
B. `Fe^2+`
C. `Mn^2+`
D. `Mg^2+`

Answer

To solve the question regarding the mineral activator involved in the transition reaction of aerobic respiration, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Transition Reaction**: The transition reaction, also known as the citric acid cycle or Krebs cycle, occurs after glycolysis. It is a crucial step in aerobic respiration where pyruvate is converted into acetyl-CoA.

2. **Identify the Role of Mineral Activators**: Mineral activators are essential for various enzymatic reactions. They assist enzymes in catalyzing biochemical reactions effectively.

3. **Focus on the Specific Reaction**: In the transition reaction, certain minerals act as activators for enzymes involved in the conversion of pyruvate into acetyl-CoA.

4. **Determine the Correct Mineral Activator**: According to the information provided, Magnesium (Mg²⁺) is identified as the mineral activator that plays a significant role in the transition reaction. It aids in the enzymatic activity necessary for the conversion process.

5. **Conclusion**: The mineral activator involved in the transition reaction of aerobic respiration is Magnesium (Mg²⁺).

### Final Answer:
The mineral activator involved in the transition reaction of aerobic respiration is Magnesium (Mg²⁺).
