Enzymes

Key Properties of Enzymes

  • usually proteins (sometimes RNA)

  • catalyse reaction in cells

  • lower activation energy of reaction that they catalyse → increasing the rate of these reaction

  • Without enzyme → high activation energy

  • With enzyme → low activation energy

  • Highly specific → active site complements shape and charge of their substrate

    • Substrate → substance that enzyme acts upon
