1. Cellular Respiration Getting Energy to make ATP!

2. Plant Energy vs. Animal Energy What would we look like if we had chlorophyll in our skin? What if all our energy was from photosynthesis? Luckily, it isn’t! Our mitochondria break down materials to give us energy!

3. Cellular Respiration Where? MITOCHONDRIA What? BREAKS DOWN FOOD TO MAKE ATP How?1) GLYCOLYSIS 2) CITRIC ACID CYCLE 3) ELECTRON TRANSPORT CHAIN Why? TO GET ENERGY in the form of ATP!!!!

4. O 2 D 2 -Hehe-a little Star Wars humor…get it? R2D2 ANAEROBIC-no oxygen required –GLYCOLYSIS AEROBIC-oxygen required –CITRIC ACID CYCLE –ELECTRON TRANSPORT CHAIN

5. GLYCOLYSIS - glyco…lysis Where? Cytoplasm What? A series of chemical reactions that break down glucose How? Breaks down glucose into 2 molecules of pyruvic acid Why? To make pyruvic acid, ATP, and NADH! p. 238

6. This is important.

8. Citric Acid Cycle (Kreb’s Cycle) Where? Mitochondria What? Breaks down acetyl-CoA to form ATP, NADH, FADH 2, and CO2 Why? Drives ETC to make huge amounts of ATP!!! p. 239

9. ELECTRON TRANSPORT CHAIN Where? Inner membrane of mitochondria What? Energized electrons move from protein to protein to O 2 How? NADH and FADH 2 give up electrons Why? To make 32 ATP!!! p.240

12. ATP FROM 1 GLUCOSE MOLECULE

13. FERMENTATION When? When cells are short on oxygen What? Anaerobic process that follows glycolysis until oxygen is available. How? Lactic Acid Fermentation (muscles) Alcoholic Fermentation (Yeast) Why? To produce ATP when oxygen is low

17. FERMENTATION (IT’S ANAEROBIC!) LACTIC ACID Glucose Pyruvic Acid Lactic Acid + 2ATP Occurs in bacteria, plants, and animals Results in muscle fatigue and soreness ALCOHOLIC Glucose Pyruvic Acid Alcohol + 2ATP + CO 2 Yeast do it

18. A Comparison Chart, p.241 Lactic acid fermentation Alcoholic fermentation Cellular respiration Glucose Pyruvic acid Lactic acid + 2 ATP Glucose Pyruvic acid CO 2 + alcohol + 2 ATP Glucose Pyruvic acid CO 2 + H 2 O + 38 ATP
