Lecture
This lecture covers the process of cellular respiration, focusing on the generation of ATP through catabolic pathways. Topics include the oxidation of organic molecules, the role of NADH and FADH2, the principles of redox reactions, and the different stages of cellular respiration. Emphasis is placed on glycolysis, the citric acid cycle, and oxidative phosphorylation. The lecture also discusses the importance of enzymes and coenzymes in capturing usable energy, the transfer of electrons through NAD+ and FAD, and the significance of NADH in ATP synthesis. Additionally, it explores the energy stored in chemical bonds containing hydrogen, the role of NAD+ as an electron carrier, and the comparison between oxidative phosphorylation and substrate-level phosphorylation.
