2 OBJECTIVES: RELATE ENERGY AND CHEMICAL REACTIONS OBJECTIVES: RELATE ENERGY AND CHEMICAL REACTIONS DESCRIBE THE ROLE OF ENZYMES DO NOW: Take out your homework. Then…is cellulose a monosaccharide or polysaccharide? Where is it found? HOMEWORK: finish concept 5 packet Review sheet due Moday.
3 Chemical reactions involve forming or breaking of chemical bonds Na + Cl NaClReactants ProductsThe chemicals involved The chemicalsat the start of a reaction produced at the end of a reaction
4 Chemical Reactions Need help to get started Ex. Match starts a fire Activation EnergyEnergy required to get a chemical reaction started
13 Factors that effect enzymes Conditions that are too hot or too acidic cause proteins to unwind or denatureDenaturing changes the shape of the active siteEnzyme can’t bind to substrateHomeostasis (temp and pH) important for enzyme function
14 Naming enzymes Most end in _______-ase Beginning tells what it does Examples:Lipase-breaks down lipidsSucrase-breaks down sucroseDNA polymerase-polymerizes DNALactase-breaks down lactoseProtease-breaks down proteins
