Answer:
The immediate source of energy that powers a cell’s activities is ATP (Adenosine triphosphate)
Explanation:
The direct source of energy for cells is ATP. When the cell needs energy , it is converted from storage molecules like carbohydrates, such as glycogen, and fats into ATP.
ATP takes chemical energy obtained from the breakdown of food molecules and releases it. The cells uses chemical energy for:
1. drive metabolic reactions
2. to transport needed substances across membranes
3. and to do mechanical work, for example in muscles movement
