What is the role of NADH and FADH2?
Understand the Problem
The question is asking about the specific functions and importance of NADH and FADH2 in biological processes, particularly in cellular respiration. These molecules are crucial as they serve as electron carriers, facilitating the transfer of energy in metabolic pathways.
Answer
They act as electron carriers that transport high-energy electrons to the electron transport chain, aiding ATP production.
The primary role of NADH and FADH2 in cellular respiration is to act as electron carriers that transport high-energy electrons to the electron transport chain in the mitochondria. This process helps in the production of ATP by driving the proton gradient needed for ATP synthase activity.

More Information
NADH and FADH2 are produced during the Krebs cycle and other metabolic pathways and are essential for ATP generation through oxidative phosphorylation.
Tips
A common mistake is to overlook their role in the electron transport chain and focus only on their production during the Krebs cycle.
