Answer 1

Question

1. The alcoholic beverages required total absence of oxygen as bacteria and yeast perform fermentation process that require no oxygen. Therefore no oxygen is not required and rest everything is required. Hence, option g is correct.

2. Cyanide is the inhibitor of cellular respiration that block electron transport chain at complex IV which is the final electron transporter in that chain. This electron transporter passes electron to terminal electron acceptor and if get blocked only 2 electrons can be transfer. Hence, option e is correct.
