This Powerpoint begins with the importance of ATP energy in the daily function of all cells. Students will then be taken step-by-step through the processes of glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis in the mitochondria. A full accounting of each of the atoms within glucose is given, from the carbon dioxie released by exhalation to the phosphorylation of ADP to ATP. Finally, students will learn about how lactic acid fermentation and ethanol fermentation may be used when oxygen is not available.
Essential concepts: Cell respiration, ATP, oxygen, glucose, glycolysis, citric acid cycle, electron transport chain, chemiosmosis, mitochondria, carbon dioxide, oxidative phosphorylation, ADP, lactic acid fermentation, ethanol fermentation.
Test questions: Available at the biology instructor resources subscription page.
