Enzyme

  1. what are co-factors
    • non protein chemical compound that binds to enzyme and activates it
    • inorganic
    • tightyly bound to an enzyme and is required for catalysis
  2. what are coenzymes
    • chemical compound that binds to enzyme
    • "prosthetic group"
    • organic
  3. what is a holoenzyme
    • a "whole enzyme"
    • = apozenyzme + coenzyme
  4. what are the factors that affect enzyme activity
    • [substrate]
    • [enzyme]
    • pH = charge of protein, too extreme may cause denaturing
    • temp = ↑ temp = ↑rxn rate, too high may denature protein

    • cofactors
    • inhibitors
  5. Which statement about enzymes is true?
    ​A. An enzyme alters the Gibb’s free energy of the reaction.​
    B. Enzymes cause a reaction with a positive free energy to occur spontaneously.
    ​C. An enzyme’s natural substrate has the highest Km.​

    D. A competitive inhibitor will alter the apparent Km of the reaction.
    D
