Substrate V Max Inhibitors Enzyme Controlled Comp Effect Lower

Non-competitive inhibitors lower Vmax permanently; competitive inhibitors do not lower Vmax and can be overcome by increasing substrate concentration.

Non-competitive inhibitors lower Vmax, while competitive inhibitors do not lower Vmax and their effects can be overcome by increasing substrate concentration.

Front Draw a graph showing how substrate conc affects rate of an enzyme-controlled reaction if a comp or non comp inhibitor is present. Explain effect of these inhibitors on Vmax of an enzyme-controlled reaction.
Back
  • Non-competetive inhibitors permanently lower the Vmax of a reaction, adding more substrate will not overcome effect of them
  • Competetive inhibitors do not lower the Vmax of a reaction, adding more substrate will result in more substrate than inhibitor and original Vmax will be reached
