1. CELLULAR RESPIRATION AND FERMENTATION

2.  ATP energy!  Needed to:  Build proteins  Copy DNA  Muscle contractions  Nerve impulses  Synthesizing hormones WHY DO ORGANISMS NEED TO RESPIRE

3. OVERVIEW OF AEROBIC RESPIRATION

4.  Aerobic= “with air” AEROBIC CELLULAR RESPIRATION This process yields 36 ATP molecules!

5. THE LINK BETWEEN PHOTOSYNTHESIS AND CELLULAR RESPIRATION

6.  Glycolysis occurs in cytoplasm  Glyco= sweet  Lysis= to break  Results in 4 ATP per molecule of glucose GLYCOLYSIS

7.  The Kreb’s Cycle and Electron transport chain occur in the mitochondrion  Produces 32 ATP molecules KREB’S CYCLE AND ELECTRON TRANSPORT CHAIN

8. OVERVIEW OF AEROBIC RESPIRATION

9. FERMENTATION Also known as anaerobic respiration= “without air”

10.  Bacteria in yogurt produce lactic acid  Animals experience muscle fatigue when lactic acid builds up LACTIC ACID FERMENTATION

11. SACCHAROMYCES CEREVISIAE

12.  This process yields 4 ATP for every glucose molecule ALCOHOLIC FERMENTATION

13. SACCHAROMYCES CEREVISIAE

14. FERMENTATION Also known as anaerobic respiration= “without air”
