How Food Becomes Energy: Metabolism and Cellular Respiration

How does a sandwich turn into a sprint? Join Bri to learn how your cells turn food into energy. We cover metabolism, catabolism and anabolism, how ATP works as the cell's battery, the three stages of aerobic respiration, and what happens when your muscles run low on oxygen. In this video we covered Metabolism: catabolism vs anabolism ATP and ADP: how cells store and release energy The cellular respiration equation (word and chemical) Aerobic respiration: glycolysis, the Krebs cycle and the electron transport chain Anaerobic respiration, lactic acid and oxygen debt Metabolic heat A past exam question worked through Common mistakes that lose marks Quiz questions to test yourself CHAPTERS 0:00 Intro 0:09 How does a sandwich become a sprint? 0:25 Learning goals 0:41 Metabolism: catabolism and anabolism 1:23 ATP: the cell's battery 2:04 Cellular respiration 2:40 Aerobic respiration: the 3 stages 3:24 Anaerobic respiration 4:06 Exam question worked through 4:32 Common mistakes 5:08 Test yourself quiz 5:56 Recap Previous episode: Surface area to volume ratio.
