| Term | Definition |
|---|---|
| atom | basic unit of matter |
| nucleus | the center of the atom which contains the neutrons and protons |
| electron | negatively charged atomic particle, located outside the nucleus |
| element | substance consisting entirely of one type of atom |
| molecule | the smallest unit of most compounds |
| catalyst` | a substance that speeds up the rate of a chemical reaction |
| substrate | reactant of an enzyme-catalyzed reaction |
| buffer | a weak acid or base that can react with a strong acid or base to prevent abrupt changes in pH |
| chemical reaction | process that changes one set of chemicals into another set of chemicals |
| reactants | elements or compounds that enter chemical reactions |
| products | element or compound produced by a chemical reaction |
| enzymes | proteins that act as a biological catalyst |
| monosaccharide | single sugar molecule |
| polysaccharides | large macromolecule formed by monosaccharides |
| DNA | deoxyribonucleic acid |
| RNA | ribonucleic acid |
| acid | compound that forms hydrogen ions (H+) in solution |
| base | compound that produces hydroxide ions (OH+) in solution |
| monomers | small unit that can join with other small units to form polymers |
| polymers | large compound formed by combinations of many monomers |
| carbohydrates | compound made by Hydrogen, Oxygen and Carbon; the main source of energy for the human body |
| nucleic acid | macromolecule containing Hydrogen, Oxygen, Nitrogen, Carbon and Phosphorous |
| nucleotides | monomer of nucleic acids made up of a 5 carbon sugar, phosphate group and a nitrogenous base |
| proteins | macromolecule that contains Carbon, Hydrogen, Oxygen and Nitrogen, needed by the body to grow, make repairs and make up enzymes |
| amino acid | compound with an amino group on one end and a carboxyl group on the other end |
| ion | atom that has a positive or negative charge |
| covalent bond | bond formed by the sharing of electrons between atoms |
| compound | substance formed by the chemical combination of two or more elements in definite proportions |
| ionic bond | bond formed when one or more electrons are transferred from one atom to another |
| cohesion | attraction between molecules of the same substance |
| adhesion | attraction between molecules of different substances |
| mixture | material composed of two or more elements or compounds that are physically mixed together but not chemically bonded |
| solution | mixture of two or more substances in which the molecules of the substances are evenly distributed |
| solute | substance that that is dissolved into the solvent to form a solution |
| solvent | substance in which the solute is dissolved into to form a solution |
| suspension | mixture of water and non-dissolved materials |
| pH Scale | measurement system used to indicate the concentration of Hydrogen ions (H+) in solution ranges from 0 to 14 |
| surface tension | the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area. An example of this is water droplets. |
