Solution

Catalyst

  • A catalyst is a substance that alters the rate of reaction in a chemical reaction.
  • These are known to undergo physical change but not a chemical change.
  • Catalyst functions even when present in small quantities.
  • Catalysts activate the rate of reaction but a reaction cannot be initiated by them.
  • Catalytic activity is known to be maximum at optimum temperature.
  • Catalyst generally increases the rate of reaction.

Inhibitor

  • Enzyme inhibitors are the polar opposite of catalysts in that they slow down the chemical process.
  • They may even stop a reaction.
  • Inhibitors are broadly classified as competitive and noncompetitive inhibitors.
  • A competitive inhibitor are known to compete with substrate for binding to an active site.
  • A non-competitive inhibitor does not attach itself to the active site, instead attaches at a different site than the active site.
