Biology

The correct answer is: B.To provide chemical energy for cellular activities.

Explanation:

ATP (Adenosine Triphosphate) is primarily known as the energy currency of the cell. Its main function is to store and transfer chemical energy within cells, which is then used to fuel a variety of cellular processes. When ATP is hydrolyzed (broken down) into ADP (Adenosine Diphosphate) and an inorganic phosphate (Pi), energy is released, which powers processes such as:

1.Active transport (e.g., sodium-potassium pump)

2.Protein synthesis

3.Muscle contraction

4.Cell division

5.Biosynthesis of molecules (e.g., DNA, RNA, lipids)
