Question

True or false. Free electrons cannot exist in the cell, they must be transferred to specialized electron carriers (NAD+)

Answer 1

Ans:- True

Explanation:- presence of electrons can leads to formation of ROS(Reactive Oxygen Species) and taking the cell into an irreversible process of self killing as ROS are further harmful to cell environment. Thus the electrons must be transferred to specialized electron carriers(NAD+). The redox molecules must undergo chemical reaction that is oxidation or reduction reactions due to which elctron can freely move to any location inside the cell.
