Learning objectives
Define enzymes as proteins that function as biological catalysts and explain why they are essential to all living organisms
Describe enzyme action in terms of the active site of the enzyme being complementary in shape to its substrate, leading to the formation of products
Explain enzyme action and specificity in terms of the enzyme–substrate complex and the complementary shape and fit of the active site with the substrate (Extended)
Investigate and describe the effects of changes in temperature and pH on enzyme activity, including the optimum and denaturation
Explain the effects of temperature and pH on enzyme activity in terms of kinetic energy, the frequency of effective collisions, the shape and fit of the active site and denaturation (Extended)
