Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these “hydrogen carrier” compounds are a source of high energy electrons? Select all that apply.
A
FAD
B
FADH2
C
NAD+
D
NADH
Explanation: 

Detailed explanation-1: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

Detailed explanation-2: -The high-energy electron carriers that are involved in cellular respiration are NADH and FADH2.

Detailed explanation-3: -NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.

Detailed explanation-4: -During cellular respiration, the energy formed in mitochondria is stored in the form of ATP which is also known as energy currency of the cell. It provides energy for all the life activities by its breakdown into ADP and Pi. ATP contains three phosphate group which has high energy bond.
