Question

Which of the following mineral plays a major role in energy storage and transfer of ADP and ATP?

• A. Phosphorus
• B. Magnesium
• C. Molybdenum
• D. Sulphur

Hint:

Phosphorus is often termed the "energy currency of the plant" because it constitutes the phosphate molecules of ADP and ATP.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Certain plant mineral nutrients are structural components of biochemical compounds essential for cellular metabolism and energetic processes.

Step 2: Detailed Explanation:
Phosphorus is a key constituent of Adenosine Diphosphate (ADP) and Adenosine Triphosphate (ATP).
The energy captured during photosynthesis or respiration is stored in high-energy pyrophosphate bonds.
The cleavage and transfer of these phosphate groups are central to metabolic energy transactions.
Without phosphorus, energy storage and chemical energy transfer in cells are impossible.

Step 3: Final Answer:
The mineral that plays this role is Phosphorus, which is option (A).
