The energy currency of the cell is-

✅Explanation: ATP (adenosine triphosphate) is the primary energy currency of cells. It provides energy for a wide variety of cellular processes, such as muscle contraction, nerve impulse transmission, and chemical synthesis. ATP stores energy in the bonds between its phosphate groups. When a phosphate group is removed from ATP, energy is released that can be used by the cell to power various functions.

📌📌Other Options:
-NADPH: NADPH is a coenzyme involved in anabolic reactions, such as photosynthesis. It carries electrons that can be used to build molecules.
-Creatine phosphate: Creatine phosphate is an energy storage molecule found mainly in muscle cells. It can donate a phosphate group to ADP to regenerate ATP, but it is not the main energy currency of the cell.

🔑Key Points:

• ATP(Adenosine Triphosphate):
-It is an organic compound composed of the phosphate groups, adenine, and the sugar ribose.
-These molecules provide energy for various biochemical processes in the body. That is why it is called Energy Currency of the Cell.
-The ATP molecule was discovered in the year 1929 by German chemist Karl Lohmann.
-These ATP molecules are synthesized by Mitochondria, therefore it is called the powerhouse of the cell.
-In the year 1948, Scottish biochemist Alexander Todd was the first person to synthesise the ATP molecule.

🛑 Additional Information:
ADP(Adenosine diphosphate): 
-Adenosine diphosphate (ADP), is an important organic compound in metabolism and is essential to the flow of energy in living cells.
-It is essential in photosynthesis and glycolysis.
-It is the end-product when adenosine triphosphate ATP loses one of its phosphate groups.
-The energy released in the process is used to power up many vital cellular processes.
-ADP reconverts to ATP by the addition of a phosphate group to ADP.
