| Question | Answer |
|---|---|
| enerqy | ability to do work |
| kinetic energy | Energy of motion |
| chemical energy | potential energy of molecules |
| potential energy | stored energy |
| enzyme | protein molecule that speeds up chemical reactions in living things by lowering the activation energy |
| substrate | reactants (beginning chemicals) acted on by an enzyme |
| active site | pocket or groove located on the enzyme that fits the substrate |
| catalase | enzyme responsible for breaking down hydrogen peroxide into water and oxygen |
| lock & key hypothesis | idea that enzymes are specifically shaped to fit only one type of substrate |
| enzyme-substrate complex | union of the substrate to the active site of the enzyme |
| -ose | endings (suffixes) found on many sugars and carbs |
| catalyst | substance that speeds up a chemical reaction without being "used up" in the reaction |
| reactant | element or compound that enters into a chemical reaction |
| product | chemical substance formed as a result of a chemical reaction |
| law of conservsation of mass | states that atoms are neither created nor destroyed in a chemical reaction |
| co-enzymes | metal ions or organic compounds that help enzymes |
| chemical reaction | a process that changes one set of chemicals into another set of chemicals |
| lipid | macromolecules used for energy storage, cell membranes, and waterproofing |
| polysaccharide | large sugar polymers |
| monosaccharide | single sugar monomers |
| carbohydrate | main source of energy for all living things |
| polymer | large molecule formed by the joining of multiple monomers |
| monomer | small units of larger molecules |
| protein | macromolecule that provides structure and regular processes for the cells |
