How Cells Make Energy: Cellular Respiration Explained

Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive overview of cellular respiration, detailing how living organisms convert chemical energy from food into adenosine triphosphate (ATP). The host explains why glucose must be broken down rather than used directly, using the analogy of breaking a large bill into smaller coins for a vending machine. The video methodically breaks down the process into its key stages: glycolysis in the cytoplasm, and the citric acid cycle (Krebs cycle) and electron transport chain within the mitochondria, highlighting the crucial role of oxygen.
