  17. Each level of Organization exhibits
    Emergent properties 
  18. What is an Emergent properties 
    It's the property where living things become more and more complex 
  19. Process in which the folding structure of a protein is altered due to exposure to certin chemical or physical factors; causing the protein to become biologically inactive
    Denaturation of a protein
  20. When you denature a protein you destroy its _______ and ____ strucutes
    Secondary and Tertiary strucutes 
  21. ________ bonds dont break
    Peptide bonds
  22. The primary stucture of a protein is what 
    amino acids 
  23. What does Chaperoin do
    Folds proteins and corrects misfolding
  24. Explain the Nitrogen Cycles
    N2 from the Atomosphere is taking in by plants and bacteria and then fixed so we can use it
  25. Plants can make their own ____ but we cant
    Amino acids

  29. Factors that can effect a enzyme
    • 1.) Tempreture
    • 2.)pH - b/c to acidic or basic it like 6-8 pH
  30. Two Types of Enzyme Inhibitor which affects enzymes
    Competive, Non competive, 
  31. What is an competive inhibitor
    Some what same shape as substrate and goes into the enzymes spot
  32. What is the noncompetive inhibitor
    Changes the shape of the substrate by going into a different spot
  33. What is allostenic regulation
    When a substate has two sites on the active and one the allostenic sites and the allostenic inhinbitor comes in and changes the shape of the substrate
  34. Tells reaction to stop
