Which of the following is known as energy currency of the cell?

Adenosine Triphosphate

The correct answer is Option (2)- Adenosine Triphosphate

The molecule known as the energy currency of the cell is Adenosine Triphosphate (ATP).

Explanation:

• Adenosine Triphosphate (ATP): ATP is a molecule that stores and transfers energy within cells. It consists of an adenine base, a ribose sugar, and three phosphate groups. The energy stored in the bonds between the phosphate groups is released when these bonds are broken, providing energy for various cellular activities.
• Adenosine Diphosphate (ADP): When ATP releases energy, it is converted to ADP (Adenosine Diphosphate) by losing one phosphate group. ADP can be recharged back to ATP through cellular processes like cellular respiration.
• Glycine Triphosphate: Glycine is an amino acid and is not typically involved in the energy currency of the cell. Triphosphate is a term used to describe molecules with three phosphate groups.
• Adenosine Phosphate: This term is not commonly used, and the primary energy carrier in cells is ATP, not Adenosine Phosphate.

In summary, ATP is often referred to as the energy currency because it serves as a universal carrier of chemical energy in cells, facilitating energy transfer for various cellular processes.
