Respiration — practice question

In aerobic respiration, most ATP is made by oxidative phosphorylation.
(a)[3]

Outline the characteristics of ATP that make it suitable as the universal energy currency.

(b)[6]

Rotenone is a substance that interferes with oxidative phosphorylation. Rotenone disrupts the first carrier in the electron transport chain by preventing electrons being transferred from this carrier. Suggest and explain how rotenone lowers the production of ATP and water in aerobic respiration.
