Q) Role of NADH and FADH2 in cellular respiration.
FAD+ + 2e- +2H+ ---------> FADH2
NAD+ + 2e- + H+ -------------> NADH
Answer:-
Q1) a)Both equations are examples of reduction reaction, because electrons are accepted.
Explanation- In reduction reactions electrons are accepted, here in both NAD+ and FAD they accept electrons.
Q1) b) In this case both FAD and NAD+ are reduced.
Explanation- as both NAD+ and FAD accepts electrons they are reduced.
Q1) c) When these reactions occur within the cell, the high energy electrons are added to the hydrogen ions are supplied to the Photosynthesis.
Explanation- When high energy electrons are added to hydrogen ions, NADH and FADH2 produced but energy is not released, the energy gets released from them, when NADH and FADH2 are oxidized in the electron transport system. The energy produced from there goes to fulfil the requirements of all the metabolic processes like photosynthesis and other metabolic activities of an organism.
Q1) d)Both of these reactions are part of a large set of individual metabolic reactions that make up the process of cellular respiration.
Explanation - These are the products of glycolysis and citric acid cycle in which NADH and FADH2 are produced. These are a part of cellular respiration which is a large set of individual metabolic reactions like glycolysis, citric acid cycle, electron-transport system.
