You may print this sheet and add your answers to this page or make a note sheet of your own.What are the three subatomic particles that make up an atom?What are their charges?Where are they located in the atom?What is an element?Know how to read your periodic table. What is the atomic number and what does it tell us? What are the atomic symbols for the first 20 elements?How can we tell the number of proton and electrons in an element? How do we calculate the number of neutrons given the atomic mass?What is a compound?What is a covalent bond? How does it form? What are some examples of covalent compounds?What is an ionic bond? How does it form? What are some examples of ionic compounds?Know the difference between an atom, an element and a compound.How is the periodic table organized? What do the columns mean?What is an acid? What is a base? Know how to read a pH scale. Review the “Cabbage pH Lab.”What are some of the pH values of your body?How do H+ ions and OH- ions relate to pH?Know the properties of water including heat capacity, cohesion, adhesion and surface tension.What makes water molecules polar?What is a buffer and how do they work? Review the buffer lab “Keep Buffered and Carry On.”Know the basic structure and functions of the 4 organic compounds: carbohydrates (sugars and starches), lipids (fats, waxes and oils), proteins (amino acids and enzymes), and nucleic acids (DNA and RNA).What are the monomers for each of the compounds? Know the shape and chemistry (see your coloring worksheet on macromolecules).What foods contain each of these compounds? How do we test for these compounds? Review your “Organic Compounds in Foods Lab.”What are the MAIN functions of each of these compounds in your body?Review enzymes and how they work. Know what a substrate, reactant, product, and active site is.What type of organic compound is an enzyme?What do enzymes do? Know the reactions for catalase and lactase as well as the paperase example.What does it mean to denature an enzyme? What can you do to denature enzymes? Review our “Catalase Lab.”Where in your body does digestion occur?Where in your body does the absorption of nutrients occur?Review drawings and diagrams of how enzymes work. I suggest looking up videos and examples online. Video Suggestions:Bozeman Biology Enzymes: —A fun introduction: Sisters Enzymes: does the liver do? Bristol Science Center: ................
