Question

Energy currency of the cell is called

• A. ATP
• B. AMP
• C. NADP
• D. ADP

Answer 1

The Correct Option is A

To solve the problem, we need to identify the molecule that is commonly referred to as the "energy currency" of the cell.

1. Understanding Cellular Energy:
Cells perform various functions that require energy. This energy is supplied and stored in the form of a molecule that can be readily used by cellular processes.

2. ATP – The Energy Currency:
ATP (Adenosine Triphosphate) is known as the energy currency of the cell because it stores and provides energy for many biochemical cellular processes by undergoing hydrolysis and releasing one phosphate group: 
ATP → ADP + Pi + Energy

3. Eliminate Other Options:
- AMP (Adenosine Monophosphate) – a lower-energy molecule
- NADP (Nicotinamide Adenine Dinucleotide Phosphate) – involved in redox reactions, not primary energy currency
- ADP (Adenosine Diphosphate) – a product of ATP breakdown, not the main energy unit

Final Answer:
The energy currency of the cell is ATP.
