Cellular respiration: mechanism and mitochondrial architecture

Section role: supports the 'Decoding the Respiration Equation' section while the teacher formalizes the cellular respiration process and mitochondrial structures built by students in the previous challenge. Slides: (1) Title — 'Decoding Cellular Respiration'; (2) Metabolism and Energy — bullets: definition of metabolic process, role of ATP as cellular energy currency; (3) The Balanced Equation — formula C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP with input and output labels; (4) Stage 1 Glycolysis — bullets: location in cytoplasm, breakdown of glucose into pyruvic acid, limited ATP yield; (5) Stage 2 The Mitochondrion — diagram of double membrane, outer membrane, inner membrane cristae, and matrix; (6) Krebs Cycle and ETC — specific locations for chemical reactions and high energy payoff; (7) Structure Meets Function — explanation of why folded cristae increase surface area for energy production; (8) Chloroplast vs. Mitochondrion — side-by-side comparison of stroma/thylakoids versus matrix/cristae; (9) Microscopic Animation — video placeholder showing molecular movement during respiration. Closing slide: 'How does the folding of the inner membrane directly affect the amount of energy a muscle cell can generate?' — sets up the efficiency check section that follows.
