Peroxisomes and Lysosomes: Intracellular Defense

The video tutorial covers the roles of peroxisomes and lysosomes in cellular defense. Peroxisomes help break down hydrogen peroxide using catalase, preventing damage from its reactive nature. The tutorial explains the dangers of hydrogen peroxide, including its reactions with UV light and iron, leading to harmful radicals. Lysosomes are highlighted for their role in phagocytosis, engulfing bacteria and breaking them down using enzymes, acid, and reactive oxidative species. The synthesis of these species is crucial for destroying microbes, showcasing the cellular defense mechanisms.
