4. Statement of Inquiry/IB Trait
The relationship between the structure and function of our parts is one way that we define what it means to be human.
IB TRAIT: KNOWLEDGEABLE, COMMUNICATORS and INQUIRERS

5. What Are Enzymes? Most enzymes are Proteins
Act as Catalyst to accelerates a reaction
DO Not permanently changed in the process

6. Enzyme Song

7. How do enzymes Work?
Enzymes work by weakening bonds which lowers activation energy
*Book model

8. Enzymes Without Enzyme With Enzyme Free Energy
Progress of the reaction
Reactants
Products
Free energy of activation

9. What Affects Enzyme Activity?
Three factors:
1. Environmental Conditions
2. Cofactors and Coenzymes
3. Enzyme Inhibitors

10. 1. Environmental Conditions
1. Extreme Temperature are the most dangerous
- high temps may denature (unfold) the enzyme. SUNLIGHT!
2. pH (most like pH near neutral) If the pH is too high or low the enzyme will not work

11. 2. Cofactors and Coenzymes
Inorganic substances such as IRON are sometimes need for proper enzymatic activity.
Example:
Iron must be present for the structure of red blood cells in order for it to pick up oxygen.

12. Denaturating Proteins
Changes in temperature & pH can denature (unfold) a protein so it no longer works
Cooking denatures protein in eggs
Milk protein separates into curds & whey when it denatures

13. Read over your enzyme lab procedures. This should be down quietly!

14. Enzyme-Substrate Complex
The substance (reactant) an enzyme acts on is the substrate
Enzyme
Joins
Substrate

15. Active Site
A restricted region of an enzyme molecule which binds to the substrate.
LOCK AND KEY
Active Site
Enzyme
Substrate

16. Competitive Inhibitor vs. Noncompetitive inhibitor
A competitive inhibitor blocks the active binding site and prevents a reaction
Noncompetitive inhibitor attaches the enzyme and changes the shape of the active site.

17. ENZYME MANIPULATIVES

18. Interesting Fact

19. Enzyme + Substrate = Product

20. What is the catalyst in this reaction?
What was the reactant? (APPLY KNOWLEDGE)

24. Possible answer
Modern prokaryotes are unicellular organelle lacking organisms that include archaebacteria and eubacteria. They can be found in nearly any environment on Earth, including volcanic vents at the bottom of the ocean and ice in Arctic and Antarctic regions

25. Objective of the day
((Obj 1) Compare the structure of prokaryotic cells with that of eukaryotic cells

26. Cells or no Cells
5 min
Make a list of those items that are comprised of cells and those items not comprised of cells. Write a rationale for each answer.

27. Possible answer
Grass, grasshoppers, and bark of tree are comprised of cells. They are either living or were once living. Rocks, soil, and water are not comprised of cells. They are nonliving

33. copyright cmassengale
Introduction to Cells
Cells are the basic units of organisms Cells can only be observed under microscope Basic types of cells:
Bacterial Cell
Animal Cell
Plant Cell
copyright cmassengale

34. copyright cmassengale
Number of Cells
Organisms may be:
Unicellular – composed of one cell
Multicellular- composed of many cells that may organize
copyright cmassengale

35. Cells May be Prokaryotic or Eukaryotic
Prokaryotes include bacteria & lack a nucleus or membrane-bound structures called organelles
Eukaryotes include most other cells & have a nucleus and membrane-bound organelles (plants, fungi, & animals)
copyright cmassengale

36. copyright cmassengale
Prokaryotes
Nucleoid region contains the DNA
Cell membrane & cell wall
Contain ribosomes (no membrane) to make proteins in their cytoplasm
copyright cmassengale

37. copyright cmassengale
Eukaryotic Cell
Contain 3 basic cell structures:
Nucleus
Cell Membrane
Cytoplasm with organelles
