Explore how amino acids at an enzyme’s active site determine substrate specificity, and how denaturation changes tertiary structure and active-site shape in IB Biology SL C1.1.7.
Some proteins in membranes act as enzymes. Outline enzyme-substrate specificity.
enzyme shape is specific to (particular) substrate;
lock and key analogy/model;
example of specific enzyme and substrate;
has specific 3-D/tertiary configuration/3-D/tertiary shape essential to functioning;
active site on enzyme binds to substrate;
substrate and active site complementary/fit together;
(substrate and active site) are complementary due to structure/chemical attraction;
enzyme-substrate complex forms;
denaturation changes enzyme's binding ability (to specific substrate);
