Carbohydrates
Proteins
Enzymes
Lipids
Nucleic Acids
PAGES: 45-49, 52, 53

5. Carbohydrates

6. Carbohydrates Names end in -ose Ringed Contain which elements? CARBO

7. Carbohydrates

12. Carb Structures
Ringed
Contain which elements?
CARBO
HYDRATE

13. Carb Purpose Quick energy source Energy storage (glycogen)
Bowel regularity (fiber)
Plant strength (cellulose/fiber)

14. PROTEIN

15. Amino Acids Building Blocks of proteins
We get them by eating foods that have protein, our bodies break down the protein and recycle the amino acids
They all have two things in common…
See if you can find it on the next slide

17. Protein

19. Protein Purpose Channels in cells Markers on cells
Main component of muscle tissue
Acts as cell transmitter (start/stop signal for processes)
Proteins from food break down into amino acids that help our bodies build/repair muscle

20. ENZYMES Names end in -ase Special kind of protein
Aid in chemical reactions
Each reaction in the body has a specific protein, so one protein can only do a certain thing

21. Enzymes

22. Enzyme Purpose Speed up chemical reactions
Used in some laundry detergents to help break down stains

23. LIPIDS

24. Lipids Lipids are fats, oils, steroids, waxes
Long chains of hydrocarbons
What elements are present?
Saturated and unsaturated

26. Saturated vs Unsaturated

28. Lipid purpose Waxes – waterproof barriers Building cell membranes
Long term energy storage

29. NUCLEIC ACIDS
Store our genetic information and use it to build proteins necessary for life processes
Built of nucleotides

31. Let’s Review Bubbl.us of organic molecules Structures
Polymers vs monomers
Elements present
Etc…

51. The Reaction

52. The Reaction In order to start it must reach what energy?
What is at the beginning, reactants or products?

53. The Reaction

54. Exergonic & Endergonic
Exer = releases
Ender = absorbs
What would an exergonic reaction do with energy?
What would an endergonic reaction do with energy?
What would happen to the temperature of the chemicals involved at the start compared to the end?

56. Adding an enzyme
What do you think would happen if an enzyme were to be added to a reaction?

58. The enzyme Lowers activation energy Reactions occur faster
WHY DO WE NEED ENZYMES?
