Agenda Essential Question? • What properties of water make it so important? Learning Goal: • I will be able to – Describe the special properties of water and explain its importance. – Explain the formation of hydrogen bonds • Notes on Properties of Water • HW: – study for 2. 2 quiz tomorrow at the end of class – 2. 2 worksheet due tomorrow

Frayer Fold Notes • You need ONE piece of paper folded “Frayer Style” • Turn to page 40 in your book.

Water & Its Importance • Why is water important for our bodies? • Water makes up 70 to 95 percent of most organisms.

Water Characteristics Page 40

What is water? Frayer NOT a Polar molecule Polar Molecule These have regions with a slightly positive and slightly negative charge so they attract, like a magnet Looks like Molecule that shares the bonds more equally examples fats & oils. What is water? Hydrogen bond The attraction between slightly positive Hydrogen atom and a slightly negative atom. One hydrogen bond is weak , but many hydrogen bonds are strong

Hydrogen bonding Demonstration • How many drops of water do you think will fit on a penny before the water breaks? • Write it on the corner of your paper and lets see who’s closest. • http: //www. youtube. com/watch? v=tv 4 Jrc 0 6 y.

Water Properties Cohesion High Specific Heat Water resists temperature changes which helps regulate cell temperatures. Adhesion Properties of water Water is attracted to other substances-creates capillary action Ex. transpiration-process when plants and trees remove water from the soil Water sticks to each other- this creates surface tension. Solvent Water is usually present in a greater amount and its polarity helps dissolve other substances.

Properties of water • High Specific Heat & Solvent http: //www. youtube. com/watch? v=QH 1 yphfgf. FI&safety_mode=tru e&persist_safety_mode=1&safe=active Return

Cohesion … Return Helps insects walk across water

Adhesion Causes Capillary Action Which gives water the ability to “climb” structures

Adhesion Also Causes Water to … Form spheres & hold onto plant leaves Return Attach to a silken spider web

Enzyme Notes 1. Copy the overall chemical equation for the process that changes glucose and oxygen into carbon dioxide and water. Circle the reactants and draw a box around the products. 6 O 2 + C 6 H 12 O 6 6 CO 2 + 6 H 2 O

Enzyme Notes 2. What is required to break bonds in the reactants? ▫ Energy is required to break bonds in the reactants. This is called BOND ENERGY which is the amount of energy needed to break a bond between two atoms.

WHAT? (it is? ) WHY? (you need it) The amount of energy needed for a chemical reaction to start. HOW? (it works) An example would be photosynthesis- a plant uses energy(activation energy) from the sun to make its food. To start chemical reactions Activation Energy p. 53 WHEN? It is used? • When you mix two solutions together. • Photosynthesis • Human making energy (Cellular respiration)

Definitions Word Catalyst Definition A substance that decreases or lowers the activation energy needed to start a chemical reaction; it increase the rate of the reaction Enzyme A protein that acts as a catalyst for chemical reactions Substrate Specific reactants that an enzyme binds with

WHY are enzymes necessary? Lock and key model To help chemical reactions in our body happen faster. What conditions affect the function of enzymes? Temperature p. H Enzymes p. 55 True or False?

True or False 1. Enzymes are involved in almost every chemical process in an organism True 2. Enzymes are catalysts True 3. All enzymes are proteins True 4.
