During the process of aerobic respiration, (i) gets oxidized and its electrons get transferred to the electron transport chain while in photosynthesis, (ii) gets oxidized to transfer molecules to the electron transport chain.
Options
- A(i)-glucose; (ii)-xanthophyll
- B(i)-carbon dioxide, (ii) -xanthophyll
- C(i)-carbon dioxide, (ii) -chlorophyll-a
- D(i) -glucose, (ii) -chlorophyll-a
Correct answer
D. (i) -glucose, (ii) -chlorophyll-a
Step-by-step solution
The electron transport chain is a series of reactions taking place in the mitochondria in both the cells as well as in photosynthesis. In aerobic cellular respiration, the glucose molecule gets oxidized and the electrons released get transferred to the electron transport chain, whereas in chloroplasts, the light helps in the conversion of water to oxygen and the chlorophyll a donates two electrons to the electron transport chain after oxidation.
