Multiple Choice
In terms of functional groups, what is the key structural difference between ATP and ADP?
A
ATP has one phosphate group, whereas ADP has three phosphate groups.
B
ATP contains adenine, whereas ADP contains guanine.
C
ATP contains ribose, whereas ADP contains deoxyribose.
D
ATP has three phosphate groups, whereas ADP has two phosphate groups.
Verified step by step guidance1
Identify the molecular components of ATP and ADP, focusing on their phosphate groups, sugar, and nitrogenous base.
Recall that ATP (adenosine triphosphate) contains three phosphate groups linked in a chain, while ADP (adenosine diphosphate) contains two phosphate groups.
Understand that both ATP and ADP share the same nitrogenous base, adenine, and the same sugar, ribose, so these are not the differentiating factors.
Recognize that the key structural difference lies in the number of phosphate groups: ATP has three, and ADP has two.
Summarize that the functional difference between ATP and ADP is primarily due to the presence of one additional phosphate group in ATP, which is critical for its role in energy transfer.
