Respiration differs from photosynthesis because respiration
AHappens only in green plant cells
BStores energy by reduction of carbon dioxide
CNeeds light and chlorophyll for the process
DReleases energy by oxidation of glucose
Answer & Solution
Correct answer: D. Releases energy by oxidation of glucose
1. The chapter section 7.2 compares respiration and burning.
2. Respiration breaks down glucose with oxygen and releases energy.
3. Photosynthesis builds glucose using CO2, water and light.
4. So option A states the difference correctly.
