Enzymes - Coggle Diagram

- - - - Lower activation energies help chemical reactions to more quickly produce products becuase less energy is needed to start the reaction.
  - - - Temperatures affect the rate of enzyme activity as they determine the number of times substrate and enzyme molecules collide. For example, increasing temperatures cause enzyme and substrate molecules to collide because of the kinetic energy. Therefore, a greater rate of reactions.
      - Temperatures that exceed the optimum temperature alter the shape of the enzyme and hence substartes cannot bind to the active site anymore. Theforefore a decrease in the enzyme activity occurs.
    - - At the optimum pH, enzyme activity is at the maximum. However changes above or beloew th pH means a decrease in enzyme activity becuase of denurated enzymes that formed.
    - - Enzyme activity increases rapidly as substrate concentrations increase. This is because of the increase in the number of collisions between substrates and enzymes. However, increases above the optimum substrate concentration will not increase the enzyme activity because the number of enzymes are not growing, only the number of substrates would be growing.
    - - As the concentrations of enzymes increase, so does the enzyme activity. however, when the concentration of enzymes increase above the optimum concentration, the enzyme activity does not increase. This is bceause the number of substrates are not sufficient enough to bind to the growing concentration of enzymes.
    - - There are two inhibitors which influence the enzyme activity:
        
        Competitive inhibitors
        
        Competitive inhibitors compete with the substrates and bind to the active site and alter the shape of the active site. Causing substrates to not be able to bind the active site anymore. There a decrease in enzyme activity occurs.
        
        Non-competitive inhibitors
        
        Non-competitive inhibitors bind somewhere on the enzyme but not at the active site and this alters the shape of the enzyme and hence substrates cannot bind to teh active site anymore. Thefore a decrease in enzyme activity.
