1. Warm Up 9/23 What biomolecule(s)….. 1. Found in the nucleus of every cell? 2. Insulates? 3. Speeds up chemical reactions? 4. Made of saccharides? 5. Contains Carbon? 6. Made of amino acids? 7. Provide short term energy storage? 8. Found in our hair and nails?

2. ON BACK OF BIOMOLECULE CHART BIOMOLECULEELEMENTSBUILDING BLOCKS FUNCTIONS WATER FOUND IN BODY: FOUND IN FOODS: SALTS FOUND IN BODY AS: FOUND IN FOODS: ACIDS FOUND IN BODY: FOUND IN FOODS: BASES FOUND IN BODY: FOUND IN FOODS:

3. WATER ELEMENTS: Hydrogen and Oxygen Building Blocks: None FUNCTIONS: 1.Dissolves substances 2.Transports materials 3.Maintains temperature 4.Hydrates

4. FOUND IN BODY: Interstitial – between tissues Intracellular-inside cells Blood Digestive tract FOODS: Liquids, fruits, many foods

5. SALTS – ionic compound pulled apart by water ELEMENTS: Oxygen and Hydrogen plus Ca, P, Na, Cl, K, Fe, I, etc. (electrolytes) BUILDING BLOCKS: Acids and bases FUNCTIONS: 1. Nerve impulses 2. Muscle contractions 3. Water balance 4. Blood pressure reg 5. Body structures 6. Vital to all body functions

6. BODY: Bones, teeth, blood, muscles, kidneys FOODS: Table salt, meats, fish, processed and canned foods, butter

7. Important to have salts in diet – Too much: small amount = out urine large amount = high blood pressure Too little: small = out of bones a lot missing = body functions stop

8. ASSIGNMENT 1 Read the article on FLUID NEEDS AND SODIUM NEEDS Take notes while you read, writing down between 10 – 15 of the most important things that stand out to you. Do this for each article.

9. ASSIGNMENT 2 Biomolecule review sheet – due next class QUIZ over your chart (front and back) next class. I will give questions exactly like the review sheet, you give the biomolecule.
