  3. What are the types of chemical reactions in the body?
  4. What is contained in the abdominal cavity?
  5. What are the major parts of a cell?
  1. a synthesis reactions: bonds are formed to join two or more atoms to make a new compound
    (ex: proteins are sythesized by the bonding of many amino acids)
    decomposition reactions: bonds are broken and a large molecule is changed to two or more smaller ones
    (ex: digestion of starch into many smaller glucose molecules)

5 True/False questions

  1. What is an enzyme and what does it do?Catalyst: speed up reactions without the use of external energy or heat

          

  2. What is active transport and how does it work?Requires energy of mechanical pressure. Water and dissolved materials are FORCED through a membrane from an area of higher PRESSURE to an area of lower PRESSURE
    (Example: formation of tissue fluid and the first step in the formation of urine)

          

  3. Describe a covalent bond?Covalent bonds share electrons between atoms
    (ex: H20 or water)

          

  4. Name some ways the body uses homeostasis?ability of the body to maintain a relatively stable metabolism and to function normally despite changes

          

  5. What is contained in the spinal cavity?Spinal vertebre
