During the process of acerobic respiration `ul((i))` gets oxidised and its electrons get transferred to the electron transport chain while in photosyntheis, `ul((ii))` gets oxidised 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

Answer

D

Explanation

The oxidative breakdown of respiratory substrates with the help of atmospheric `O_(2)` is known as aerobic respiration. In involves complete breakdown of substrates into `CO_(2)` and water, releasing energy. For example, the simple chemical equation for aerobic breakdown of glucose is
`C_(6)H_(12)O_(6)+6O_(2)rarr6CO_(2)+6H_(2)O+3870 kJ//686 KCal`
When during photosynthesis chlorophyll a gets oxidised to transfer molecules to the electron transport chain.
