AP BIOLOGY

Detailed explanation-1: -The correct answer from the available option as to which can be compared to a battery in need of recharging would be ADP . ADP, Adenosine Diphosphate functions in the metabolism of energy in the body system of living organisms.

Detailed explanation-2: -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-3: -The relationship between ATP and ADP can be compared to the state of a battery. Which of the following statements BEST compares ATP, ADP and a battery? ADP is full of energy like a charge battery. ATP is full of energy like a charged battery.

Detailed explanation-4: -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. ADP also has high energy bonds located between each group.

Detailed explanation-5: -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.
