Episode 12 begins with a Latin lesson, spirare. Melanie pulls the oldest three stooges trick in the book to remind students of the products of cellular respiration (1:25). The star of the show is introduced (2:20) with a reminder of the importance of surface area to volume ratios. Cellular respiration is explored in three steps: Glycolysis (2:50), the Krebs Cycle (3:55), and ETC (5:08). Melanie checks in on the tallies of reactants and products (4:43). Don’t forget that oxygen is the final electron acceptor! (5:40). Deep breath in, deep breath out - Repeat as needed (6:35).
The Question of the Day (7:13) asks “Which step of cellular respiration will still occur under anaerobic conditions?”
