1. Objective: To be able to describe cellular respiration, lactic acid and alcohol fermentation.

2. To be able to describe cellular respiration. Cellular Respiration 6O 2 + C 6 H 12 O 6  6CO 2 + 6H 2 O + energy Releases energy by breaking down glucose and other food molecules when oxygen is present.

3. To be able to describe cellular respiration. Glycolysis Process when glucose is broken in half to produce 2 molecules of pyruvic acid (3 Carbon molecules)

4. To be able to describe cellular respiration. ATP has to invest 2 ATP in the beginning gets 4 back at the end net gain= 2 ATP

5. To be able to describe cellular respiration. NADH During glycolysis 4 high-energy electrons are passed to a carrier called NAD+ this is converted into NADH Glycolysis does not require oxygen!!

6. To be able to describe fermentation. Fermentation- No Oxygen (anaerobic) releases energy from food molecules w/o oxygen Two Types: Alcoholic Fermentation and Lactic Acid Fermentation

7. To be able to describe alcohol fermentation. Alcoholic Fermentation- pyruvic acid + NADH  alcohol +CO 2 + NAD + Causes bread to rise

8. To be able to describe lactic acid fermentation. Lactic Acid Fermentation- pyruvic acid  converted to lactic acid and regenerates NAD + pyruvic acid+ NADH  lactic acid + NAD + sore muscles when exercise and not enough O 2 is available burning sensation
