  1. Cellular Respiration Ex 8

  2. Cellular respiration • Break bonds in nutrients to form ATP • Where does it occur In eukaryotic cells? Mitochondria

  3. Overall reaction is aerobic Glucose + Oxygen  Carbon dioxide + Water Net 36 ATP

  4. Fermentation • An alternative to cellular respiration in some cells, produces 2 ATP/glucose only • Glucose  CO2 + ethanol + 2 ATP

  5. CO2 production as a measure of fermentation See handout Assignment 7 Hypothesis: Fermentation of glucose, sucrose, and starch by yeast occurs at the same rate Yeast producing CO2

  6. CELLULAR RESPIRATION Assignment 2: Hypotheses: Living organisms do not produce CO2 Experiment 1 air exhaled from lungs vs room air

  7. CO2 production as a measure of cellular respiration Colorimetric test Bromthymol blue + CO2 yellow color What is the dependent variable? Cellular respiration Glucose + Oxygen  Carbon dioxide + water Net 36 ATP

  8. Experiment 2 Hypotheses: Living organisms do not produce CO2 Plant vs animal What is the independent variable?

  9. Assignment 3: Hypothesis: Carbon dioxide does not accumulate in photosynthesizing cells Plants in light vs dark
