Answer 1

Answer 65: correct option is (vi)

Cyanide works by stopping oxygen from picking up electrons from the electron transport chain. It most like to stop most atp production.Normally oxygen acts as a final electron receptor at the end of the electron transport chain. Cyanide disrupts the electron transport chain by binding to the enzyme cytochrome c oxidase. This prevents the transport of electrons from cytochrome oxidase to oxygen. Without oxygen, the cell is unable to produce ATP aerobically. All other options are not correct .

Answer 64:correct option is (ii).

koch's postulates require testing how bacteria causes disease.Koch's postulates are important because they were one of the first methods doctors used to identify the cause of a disease.All other options are not correct.

ANSWER 62: correct option is (v).

Carbon dioxide undergoes reduction during dark reactions. During the dark reaction, NADPH2 and ATP are used to reduce carbon dioxide into sugars.

All other options are not correct.
