1. Fatty Acid & Protein Metabolism

2. Carbohydrate metabolism is WAY groovy baby! But what does Jon expect us to know from all this chemistry mumbo jumbo?

3. Where is Carbohydrate Metabolism? Glycolysis ___________________ Krebs Cycle ___________________ ETS ___________________

4. When Is Oxygen Required? Glycolysis_________________ Krebs Cycle_________________ ETS_________________

5. What is Produced? Glycolysis__________________ Krebs Cycle__________________ ETS__________________

6. Outline I.Anaerobic Metabolism II.Fat Metabolism A. Ketoacidosis B. Diabetes Mellitus III. Protein Metaboism

7. Aerobic vs. Anaerobic Respiration Only gylcolysis can occur without O 2

8. Aerobic vs. Anaerobic Respiration Only gylcolysis can occur without O 2 Anaerobic Metabolism: 1. Inefficient and cannot be sustained for long periods

9. Anaerobic Metabolism Occurs during strenuous exercise O 2 cannot be delivered to cells fast enough for Krebs Cycle

10. Outline I.Anaerobic Metabolism II.Fat Metabolism A. Ketoacidosis B. Diabetes Mellitus III. Protein Metaboism

11. You Don’t Just Eat Carbohydrates Big Mac Nutrition Facts: Calories 500 Protein (g) 25 Carbohydrates (g)42 Total Fat (g)26 Saturated Fat (g) 16 Sodium (mg) 890

13. Structure of Triglycerides

14. Metabolism of Fats Fats broken into parts that enter glycolysis and Kreb’s cycle

15. Metabolism of Fats Fats broken into parts that enter glycolysis and Kreb’s cycle Fats and Carbohydrates can be stored

16. You Need Some Carbs to Burn Fat “Fats Burn in the Fire of Carbohydrate Metabolism” 2 Carbon 6 Carbon 4 Carbon

17. Without Glucose, Ketoacidosis Occurs Example: Acetone

18. Metabolic Disorder: Diabetes Mellitus Ketoacidosis occurs in Type I Diabetes

19. Metabolic Disorder: Diabetes Mellitus Ketoacidosis occurs in Type I Diabetes Lack of insulin causes hyperglycemia

20. Metabolic Disorder: Diabetes Mellitus Ketoacidosis occurs in Type I Diabetes Lack of insulin causes hyperglycemia Dehydration and sweet taste to urine

21. Dangers of Ketoacidosis Blood pH drops Fruity smell to breath Diabetic Coma Death results

22. Outline I.Anaerobic Metabolism II.Fat Metabolism A. Ketoacidosis B. Diabetes Mellitus III. Protein Metabolism

23. Protein Metabolism Last resort for energy Why might this be?

24. Protein Metabolism Most is converted into glucose

25. Protein Metabolism Most is converted into glucose Some broken down into Urea

26. Summary Carbohydrates, Fats, and proteins are all used for energy (in that order) Without oxygen, pyruvate is converted to lactate Ketoacidosis occurs in diabetics lacking glucose metabolism
