Mitochondria Overview: Structure and Function

The video tutorial covers the protective organelles like peroxisomes and lysosomes, and then shifts focus to the mitochondria, highlighting its structure, function, and importance in energy production. It explains ATP as the energy currency of cells and details the metabolic pathways occurring in mitochondria, such as the TCA cycle and beta oxidation. The tutorial also discusses heme biosynthesis and related disorders like porphyrias, concluding with practical applications for understanding mitochondrial functions.
