Question

During the process of aerobic respiration;

(i) gets oxidized and its electrons get transferred to the electron transport chain while in photosynthesis

(ii) get oxidized to transfer molecules to the electron transport chain.

Identify (i) and (ii).

• A. (i)-glucose; (ii)-xanthophyll
• B. (i)-carbon dioxide, (ii)-xanthphyll
• C. (i)-carbon dioxide, (ii)-chlorophyll-a
• D. (i)-glucose,(ii)-chlorophyll-a

Answer 1

Answer: (D)

(i)-glucose,(ii)-chlorophyll-a

Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration. In chloroplasts, light drives the conversion of water to oxygen and NADP⁺ to NADPH with transfer of H⁺ions across chloroplast membranes.

So, the correct answers are "(1)- Glucose, (2)- Chlorophyll-a."
