  • What are large multicellular organisms made up of
    organ systems
  • What is a tissue
    A group of cells that act together to perform a specific function.
  • What is muscular tissue
    A tissue that contracts to move whatever it's attached to
  • What is glandular tissue?
    A tissue which makes and secrete chemicals like enzymes and hormones
  • What is epithelial tissue
    Covers parts of the body
  • What is an organ
    A group of different tissues that work together to perform a certain function.
  • What is an organ system
    A group of organs working together to perform a particular function
  • What is an enzyme
    biological catalyst
  • What is a catalyst?
    Increases speed of the reaction without being used up
  • Wha are enzymes made of
    Chains of amino acids
  • What is the active site
    The active site is the region on the enzyme where the substrate binds.
  • What is the optimum temperature?
    Where the enzyme is the most active
  • What happens if the temperature gets too high
    Bods holding the enzyme break
    Shape of the active site changes
    Substrate can't bind
    Enzyme is denatured
  • What happens if the pH is too high or low
    Interferes with the bonds
    Shape of active site is changed
    Enzyme is denatured
