Question

1. true or false 1 point oxidizing agents accept electrons. true false 2. multiple choice 1 point electrons enter the electron - transport chain at either complex i or ii. electrons entering through complex i are donated by which of the following? fadh2 nadh fad coq none of the other answer options is correct. 3. true or false 1 point true or false? both nadh and molecular oxygen serve as electron acceptors in cellular respiration. true false

Explanation:

1.

Oxidizing agents are substances that accept electrons in a redox - reaction. In cellular respiration, they play a crucial role in the electron - transfer process. So the statement "Oxidizing agents accept electrons" is True.

Electrons from NADH enter the electron - transport chain at complex I, and electrons from FADH₂ enter at complex II. So electrons entering through complex I are donated by NADH.

In cellular respiration, molecular oxygen is the final electron acceptor, but NADH is an electron donor (it donates electrons to the electron - transport chain). So the statement "Both NADH and molecular oxygen serve as electron acceptors in cellular respiration" is False.

Answer:

True
