Question

1. which one is like a charged battery atp or adp? 16. which is like an uncharged battery atp or adp? 17. when a phosphate bond is created, energy is. 18. when a phosphate bond is broken, energy is. 19. which one has more energy atp or adp? 20. why does adp have less energy than atp?

Explanation:

1. ATP has high - energy phosphate bonds and is like a charged battery as it can release energy when the bonds are broken. ADP has one less phosphate group and less energy, so it's like an uncharged battery.
2. ADP is like an uncharged battery as it has fewer high - energy phosphate bonds compared to ATP.
3. When a phosphate bond in ATP is broken, energy is released for cellular processes. When a phosphate bond is created (ADP + Pi → ATP), energy is stored.
4. When a phosphate bond in ATP is broken, energy is released for use in various cellular activities such as muscle contraction, active transport, etc.
5. ATP has more energy because it has three phosphate groups and the bonds between the second and third phosphate are high - energy bonds. ADP has two phosphate groups and less energy - storing capacity.
6. ADP has less energy than ATP because it has one less phosphate group and thus fewer high - energy phosphate bonds. ATP's extra phosphate group allows it to store more chemical energy.

Answer:

1. ATP is like a charged battery.
2. ADP is like an uncharged battery.
3. Energy is released when a phosphate bond in ATP is broken; energy is stored when a phosphate bond is created.
4. Energy is released.
5. ATP has more energy.
6. Because it has one less phosphate group and fewer high - energy phosphate bonds.
