1. Energy Currency: ATP is the primary energy carrier in cells. It stores chemical energy released from the breakdown of food molecules (like glucose) in its phosphate bonds. When a cell needs energy to perform a task, it breaks down ATP, releasing energy and converting it to ADP (adenosine diphosphate) and a free phosphate group.
2. Metabolic Reactions: ATP is also used directly to power many metabolic reactions within the cell. It can donate its phosphate group to other molecules, activating them and allowing them to participate in reactions that would otherwise be energetically unfavorable.
