객관식
Which of the following statements is true?
A
ADP contains more potential energy than ATP.
B
Following hydrolysis, ATP can give off one phosphate group and usable energy, whereas ADP cannot.
C
The energy produced by ATP comes from the breaking of the bond between two phosphate groups.
D
AMP and ADP contain the same amount of potential energy.
검증된 단계별 안내1
Understand the structure of ATP (adenosine triphosphate) and ADP (adenosine diphosphate). ATP consists of three phosphate groups, while ADP has two.
Recognize that the potential energy in ATP is stored in the high-energy bonds between its phosphate groups, particularly the bond between the second and third phosphate.
When ATP undergoes hydrolysis, it loses one phosphate group, converting into ADP and releasing energy. This energy release is due to the breaking of the bond between the second and third phosphate groups.
Compare the potential energy of ATP and ADP. Since ATP has an additional phosphate group compared to ADP, it contains more potential energy.
Evaluate the statement about AMP (adenosine monophosphate) and ADP. AMP has only one phosphate group, so it contains less potential energy than ADP, which has two phosphate groups.
