AP BIOLOGY

Detailed explanation-1: -The ATP molecule is just like a rechargeable battery. When it’s fully charged, it’s ATP. When it’s run down, it’s ADP. However, the battery doesn’t get thrown away when it’s run down–it just gets charged up again.

Detailed explanation-2: -ATP is Recyclable The cell doesn’t have to make ATP from scratch every time it needs some energy. Like a rechargeable battery, ATP can also be recharged and reused. ADP, the “uncharged” version of the molecule, stands for adenosine diphosphate.

Detailed explanation-3: -ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be “recharged” to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.

Detailed explanation-4: -It functions similarly to a rechargeable battery. When ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it.
