Check your neighbor • An enzyme is made from which of the following biomolecules? • • Carbohydrate Lipid Protein Nucleic Acid

What Happens When Matter Changes? • Energy is the ability to change or move

What Happens When Matter Changes? • Energy is the ability to change or move matter Type of Change Description Examples Chemical Change A substance changes into another substance Burning wood, cooking food, rust, Only the form of the substance changes Melting ice, boiling water, chopping wood, dissolving salt in water, watermelon drop AKA Chemical Reaction Physical Change

Exit Ticket • Describe the difference between a physical change and a chemical change

Exit Ticket • Describe the difference between a physical change and a chemical change and give one example of each.

What is a Chemical Reaction? • A chemical change • Reactants Products • CO

What is a Chemical Reaction? • A chemical change • Reactants Products • CO 2 + H 2 O C 6 H 12 O 6 + O 2 • Reactants- substance(s) that are changed • Products- the new substances that are formed • means changes or forms (yields)

Law of Conservation of Matter • Matter cannot be created or destroyed in a

Law of Conservation of Matter • Matter cannot be created or destroyed in a chemical reaction • Equations must be balanced, has the same number of each element on side of the equation. • EX. Mg + O 2 Mg. O

Exit ticket • What are the reactants and products in this equation? Is it

Exit ticket • What are the reactants and products in this equation? Is it balanced? • CH 4 + O 2 CO 2 + H 2 O

What is a Chemical Reaction? • Metabolism – total of all chemical reactions that

What is a Chemical Reaction? • Metabolism – total of all chemical reactions that occur in an organism • Energy is released (exothermic) from these reactions & or taken in (endothermic) • Activation Energy - amount needed for a reaction to occur • Types of Reactions in Organisms Synthesis “building up” Decomposition “Breaking-down”

What is an Enzyme & how do they promote reactions? • Catalyst- reduce the

What is an Enzyme & how do they promote reactions? • Catalyst- reduce the amount of energy needed for a reaction • Enzyme – a protein that acts as a catalyst in two ways 1. lowers activation energy needed 2. binds reactants together Active Site – place where reactant can bind Substrates – substances (reactants) that can bind to a specific enzyme
