Cell Energy Production: Metabolic Signaling

This lecture delves into the intricate processes of cell energy production, focusing on metabolic signaling pathways, glycolysis, TCA cycle, and oxidative phosphorylation. The discussion includes the coordination between the TCA cycle and OXPHOS, the role of NADH and FADH2, and the chemiosmotic coupling in mitochondria. The presentation also covers the proton-motive force across the inner mitochondrial membrane and its significance in ATP production and metabolite transport. Various transport processes across the inner membrane are explored, highlighting the interplay between electrochemical gradients and transport mechanisms.
