Answer:bath correct answer is option B
ATP is a good source of energy for cells because it provides excess energy for cellular reaction.
Explanation: ATP (Adenosine Triphosphate) is the product of the first stage of photosynthesis, it converts glucose to pyruvate to be used for cellular reactions.
It plays a vital role in providing energy for the cell, when a cell needs energy,it removes a phosphate from ATP and releases energy, this leaves Adenosine Diphosphate and free phosphate left over.
