Cellular Energy: From Food to ATP

This lecture covers the process of cellular energy production, from the conversion of food into ATP to the mechanisms of photosynthesis and respiration. It explains the energy conversion in cells and cars, the role of mitochondria in ATP synthesis, and the relationship between photosynthesis and respiration. The lecture also discusses the different types of muscle fibers, the importance of enzymes in metabolic reactions, and the concepts of catabolic and anabolic pathways. Additionally, it explores how enzymes accelerate reactions and couple energetically favorable and unfavorable reactions to drive cellular processes.
