AP BIOLOGY

Detailed explanation-1: -ATP (adenosine triphosphate) stores more energy than ADP (adenosine diphosphate). ATP has three phosphate groups with high energy bonds located between each group. ADP has only two phosphate groups.

Detailed explanation-2: -ADP contains more potential energy than ATP. Following hydrolysis, ATP can give off one phosphate group and usable energy, whereas ADP cannot. The energy produced by ATP comes from the breaking of the bond between two phosphate groups.

Detailed explanation-3: -ADP is continually converted to ATP by the addition of a phosphate during the process of cellular respiration. ATP carries much more energy than ADP. As the cell requires more energy, it uses energy from the breakdown of food molecules to attach a free phosphate group to an ADP molecule in order to make ATP.

Detailed explanation-4: -The breakdown of one glucose molecule is enough to make around 38 molecules of ATP. So, clearly, glucose has a lot more stored energy than ATP does.

Detailed explanation-5: -The molecule that stores the most energy is the molecule that is capable of carrying as much energy as possible, and it can only be carried by ATP.
