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  CO 2 + ethanol + 2 ATP

5. CO 2 production as a measure of fermentation Assignment 7 Hypothesis: Fermentation of glucose, sucrose, and starch by yeast occurs at the same rate Yeast producing CO2 See handout

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

7. CO 2 production as a measure of cellular respiration Colorimetric test Bromthymol blue + CO 2  yellow color Cellular respiration Glucose + Oxygen  Carbon dioxide + waterNet 36 ATP What is the dependent variable?

8. Experiment 2 Hypotheses: Living organisms do not produce CO 2 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
