Explore the electron transport chain's role in cellular respiration. Learn how NADH and FADH2 contribute to ATP production. Discover how energy is released when electrons transition from high to low energy states, creating a proton gradient that drives ATP synthase.
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.
Why do we need oxygen? How do we form carbon dioxide? Learn about cellular respiration, glycolysis, aerobic respiration, the electron transport chain and more. This unit is aligned to the Class 11 NCERT curriculum.
