1. The ability to do work or bring about a change

2. ENERGY

3. Food is specifically called _________________ energy, because energy is stored in its bonds.

4. Chemical Energy

5. Looking at the picture of Max on a slide, indicate where you would find kinetic and potential energy

6. Potential-On top of the slide Kinetic-Once Max goes down the slide

7. The boys are eating and then join a soccer game. Where would you find mechanical energy and chemical energy?

8. Chemical energy is found in our food, we break it down metabolically and convert it into mechanical energy (motion)

9. What is the First Law of Thermodynamics?

10. Energy cannot be created or destroyed, but can be changed from one form to another. (Conservation of Energy)

11. The 2 nd Law of Thermodynamics states that energy cannot be changed from one form to another without a loss of usable energy. What is the “useable energy” usually released as?

12. Heat

13. The relative amount of disorganization is called:

14. Entropy

15. Which room is more stable and would therefore favor the laws of entropy?

16. The messy one is more stable. The clean one requires more “work” to stay clean.

17. Explain the difference between endergonic and exergonic reactions

18. Endergonic- require an input of energy (cold pack) Exergonic-releases energy (explosion)

19. What is the difference between anabolic and catabolic?

20. Anabolic-The building up or synthesis of molecules Catabolic-The breaking down of molecules

21. What does ATP turn into after it has been hydrolyzed by water and has given off energy?

22. ATP is broken down by water (hydrolysis) gives off energy and heat and turns into ADP

23. Describe how endergonic and exergonic reactions are “coupled” in lifting weights

24. ATP breaks down to release energy (exergonic) your muscles use that energy to contract (endergonic)

25. List the 3 types of “work” that ATP can be used for

26. Chemical work, transport work and mechanical work

27. Enzymes are metabolic catalysts that lower the _________________, so that the reaction can occur quicker.

28. Energy of Activation, or Ea

29. The change in energy of the products from the reactants is written as_________________________

30. DELTA G

31. An enzyme that would break down the sugar Maltose, would most likely be named:

32. Maltase

33. What are the 6 factors affecting enzymatic speed?

34. Temperature pH Substrate concentration Enzyme Activation Enzyme Inhibition Enzyme Cofactors

35. When an Enzyme can no longer bind to its substrate because of exposure to high heat, we say that the enzyme has been:

36. Denatured
