This video covers section 3.6 of the AP Biology curriculum, focusing on how cellular respiration extracts energy from the bonds of glucose (and other biological macromolecules). Unlike photosynthesis, cellular respiration is the most ubiquitous process in nature - it is present in plants, animals, fungi, and single-celled organisms. While most plants, animals, and fungi rely on aerobic respiration, most organisms also use fermentation (anaerobic respiration) as a backup for when there is no oxygen. We’ll start with an overview of cellular respiration. Then, we’ll dive into the processes of glycolysis and fermentation. We will follow the products of glycolysis as they enter mitochondria and the Krebs cycle (citric acid cycle). Finally, we’ll see how the electron carrier molecules created throughout these initial steps of aerobic respiration go on to power an electron transport chain that generates massive amounts of ATP!
