4. Students will be able to describe different types of bonds and their energies. Explain why ATP is a high energy molecule.

5. Energy

6. How is Food Energy Captured?

7. Question: What is a calorie? Answer: A unit of energy.

8. Mr. T’ s Tidbit Topics Recall: Chemical bonds in monomers contain energy. Learn: Food consists of complex molecules that contain energy. –These large molecules are broken down by hydrolysis into monomers. –Energy is captured as ATP. Goals: –Recognize the role of digestion in energy production. –Predict which macromolecules contain the most energy.

9. Question: Where does carbohydrate digestion occur in the body? a.Inside the mouth b.Inside the stomach c.In the bloodstream d.Inside the small intestine e.Both (a) and (d)

10. Carbohydrate Digestion Carbohydrate Polymer Monomers

11. Hydrolysis of Carbohydrates Polymer H2OH2O Disaccharide Monomers H2OH2O

12. Question: At this point in the digestion of glucose polymers to glucose monomers, do you think that the body has captured any energy? a.Yes b.No c.I don’t know

13. Cell Glucose ATP Glucose must enter the cell before its energy can be stored in ATP.

14. Exercise: Predict the Molecule that Contains the Greater Amount of Metabolic Energy. (Use the examples provided on your table.)

15. Predict which Molecule Contains the Greater Amount of Metabolic Energy. Group 1: Compare a pentose (left) and a hexose (right) A) B)

16. Predict which Molecule Contains the Greater Amount of Metabolic Energy. Group 2: Compare a triglyceride (left) and a trisaccharide (right) A) B)

17. Predict which Molecule Contains the Greater Amount of Metabolic Energy. Group 3: Compare two fatty acids A) B)

18. Predict which Molecule Contains the Greater Amount of Metabolic Energy. Group 4: Compare two hexoses A) B)

19. Predict which Molecule Contains the Greater Amount of Metabolic Energy. Group 5: Compare a fatty acid and a triglyceride A) B)

20. “Wrap”ping Up, Looking Forward Disclaimer: No snickers bars were captured in the production of this tidbit.... sadly ATP Digestion
