Explanation / Answer

6. Fermentation is a metabolic process that involves anaerobic breakdown of glucose, to generate alcohol, or organic acids, and gases.

The reactions involved, during alcohol fermentation by yeast to generate Ethanol:

Answer: b.

7. Herbicides like triazines, phenylurea, nitriles, etc., act as photosynthetic inhibitors, as they bind to photosynthetic pigments. Photosynthetic pigments) like chlorophyll) are essential for absorbing solar to activate electrons.

Answer: c.

8. In photosynthetic green algae, radiolabeled carbon (14C), will be taken as carbon dioxide during photosynthesis. This will follow the Calvin cycle and get incorporated in RuBP, glyceraldehyde-3-P, sugar (glucose).

Answer: d
