1. Do Now: How do you get your energy? Homework: pg #85 # 1-5 ****EXAM TUESDAY!!!! (Cell transport and cell processes, microscope)*****

2. Production of ENERGY (ATP) Need nutrients (glucose) to make energy needed perform various activities

3. Aerobic Respiration Anaerobic Respiration Where does cellular respiration happen??

4. Do Now: Describe the process of aerobic respiration. Where does it occur? Homework: Enjoy your weekend!!!! ****EXAM TUESDAY!!!! (Cell transport and cell processes, microscope)*****

5. Aerobic Respiration Oxygen is used to produce ATP Occurs in mitochondria C 6 H 12 O 6 + O 2  CO 2 + H 2 O + 36ATP energy

6. Glucose + Energy Oxygen Carbon Dioxide Water + +

7. Anaerobic Respiration Oxygen is NOT used to make energy Only 2 ATP produced Fermentation 2 Types:

8. 1. Alcohol Fermentation Occurs in yeast and bacteria Important to the brewing and baking industries C 6 H 12 O 6  ethyl alcohol + CO 2 + 2 ATP

9. 2. Lactic Acid Fermentation Occurs in animals (muscle cells) Can lead to muscle fatigue C 6 H 12 O 6  lactic acid + 2 ATP

10. Summary Aerobic Respiration Glucose + Oxygen  Carbon Dioxide + Water + 36 ATP C 6 H 12 O 6 + O 2  CO 2 + H 2 0 + 36 ATP

11. Anaerobic Respiration Ethyl Alcohol Fermentation Glucose  Ethyl Alcohol + CO 2 + 2 ATP Lactic Acid Fermentation Glucose  Lactic Acid + 2 ATP

12. What is photosynthesis? Process in which plants use sunlight (energy) to produce glucose (food) Process in which plants use sunlight (energy) to produce glucose (food) Form of autotrophic nutrition – the ability to make food Form of autotrophic nutrition – the ability to make food Occurs in chloroplasts Occurs in chloroplasts

13. What is the equation for photosynthesis? 6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2 Raw materials Products sunlight chlorophyll GLUCOSE Waste – Into air
