Diagram a water molecule including its electrons on the board What is surface tension? What is Cohesion? What is the type of bond between Oxygen and Hydrogen in water? How do humans use water to cool themselves? What is matter made of? What is the difference between an element and a compound? What type of bond involves the sharing of electrons? What type of bond involves the gain or loss of electrons? If a solution has a pH of 10, is it acidic or basic? What is Homeostasis? What are the three atoms found in carbohydrates? Name two examples of a Disaccharide. What is the chemical formula for Glucose and Fructose? Glycogen is and example of what type of carbohydrate…. Monosaccharide, Disaccharide, or Polysaccharide? When two compounds have the same chemical formula, but different structures (such as glucose and fructose) they are known as what? What Disaccharide is formed when Glucose and Fructose join? All Organic Compounds contain what element? Name the organic compounds that are made of atoms in a 1:2:1 ratio. In what type of foods are carbohydrates found? What is “macromolecule” another name for? What polysaccharide provides structure and support for plants? Carbohydrates are a key source of what? Why are lipids (like oil) insoluble in water? Animal fats, butter and lard are examples of what kind of fatty acid? Fats are made of a glycerol molecule bonded to how many fatty acids? What type of bond can be found in unsaturated fats? Name a function of fat? What are the four types of Lipids? F-Ph-------St----Wa--- What type of monomer is a protein made of? How many different amino acids are found in proteins? Proteins that promote chemical reactions are called what? What is the most abundant protein in your body? What do antibodies do? What type of protein is responsible for carrying oxygen from the lungs to the body tissue? Where are nucleic acids found? What are the two types of nucleic acids? What are nucleic acids made of? How does an enzyme affect a chemical reaction? What is a substrate? Where does a substrate attach to an enzyme? 70% Water molecule The attractive force between water molecules at the surface. This is what allowed the water to resist spilling over when the pennies were added to the full glass of water in class. An attraction between substances of the same kind. (water sticks to water) Covalent Bond By sweating Atoms An element is made of the same kind of atoms, while a compound is made of two or more different atoms. Covalent Bond Ionic bonds Basic The process of maintaining stable internal conditions, in spite of changes in the external environment. Carbon, Hydrogen, Oxygen Lactose (milk sugar) Sucrose (table sugar) C6H12O6 Polysaccharide Isomers Sucrose (table sugar) Carbon Carbohydrates Fruits, Vegetables, & Grains Polysaccharide Cellulose Energy Because lipids are non-polar molecules, and water is polar. Saturated Three “double” covalent bond 1. Protection from trauma 2. Prevent heat loss 3. Energy storage Fats, Phospholipids, Steroids, and Waxes. (there are also plant pigments) Amino Acid 20 Enzymes Collagen Help fight infections in the body. Hemoglobin In all of your cells. DNA & RNA Nucleotides It increases the speed of a chemical reaction by reducing the activation energy. The substance on which an enzyme acts during a chemical reaction. At the active site.
