Which of the following in the stimulus is a high-energy compound?
Think it through first, then pick an option.
- a ADP
- b Chlorophyll
- c A
- d Light
Answer and explanation
Correct answer: c A
A, made from ADP + Pi with light and chlorophyll, is ATP, a high-energy compound.
Why the other options are wrong
- a ADP: ADP is the form before the phosphate is added; the high-energy compound is ATP.
- b Chlorophyll: Chlorophyll traps light but is not itself a high-energy compound.
- d Light: Light is a source of energy, not a compound.
