  1. Define: Atoms
    Microscopic particles that are units of enegy
  2. Define: Molecule
    Atoms that have become bound together
  3. Define: Compound
    Different types of atoms that bind to create substances
  4. Define: Element
    Identical atoms that bind to create substances (the periodic table lists the basic elements)
  5. Define: Inorganic compounds
    Comprised of molecules that do not contain carbon atoms (inorganic compounds found in the body cells and tissues are water, salt, acids, and bases.)
  6. Define: Organic Compounds
    Comprised of molecules that do contain carbon and generally contain hydrogen as well (true building blocks of the cell. Examples include, Carbohydrates, lipids, proteins, and nucleic acids.)
  7. Define: Ion
    Charged particle of matter (positively or negatively charged)
  8. Define: Electrolyte
    Compound containing charged particles (ions) that conducts an electrical current.
  9. Define: Acid
    Electrolyte compound that releases hydrogen ions (H+) when dissolved in water; a compound with a pH below 7.
  10. Define: Base
    Substance whose molecule or ion is capable of combining with a proton (hydrogen ion) to form a new substance; alkaline; substance having a high number of hydroxide ions (OH-) and with a pH above 7.
  11. Define: Glucose
    The simplest sugar used and stored by the body. It serves as the richest source of energy for cellular activities.
  12. Define: Carbohydrate
    Molecular compound containing a mixture of hydrogen, carbon, and oxygen atoms; breaks down into the simple sugar glucose, which is used by the body to produce energy.
  13. Define: Lipid
    Group of organic compounds made of carbon, hydrogen, and oxygen atoms. Occurring in different ratios and arrangements.  The body uses it form important cellular structures as well as hormones.
  14. Define: Proteins
    • Organic molecule made of carbon, hydrogen, oxygen, and nitrogen; breaks into amino acids.
    • Serve as the building blocks for structural framework of all cells and tissues.
  15. Define: Amino acids
    Molecular building block of protein.
  16. Define: Nucleic acids
    Very large complex molecules that differ from proteins due to the presence of phosphorus in addition to the carbon, hydrogen, oxygen, and nitrogen atoms. Found in the nucleus of the cells (DNA and RNA)
