watch the Sucrase changing the shape of its active site to become complementary to the active site.
Allosteric inhibition - Enzyme have an alosteric site. This allows products be bind to the allosteric site changing the chape of the active site preventing the formation of enzyme substrate complexes.
Allosteric inhibition allows the control of metabolic pathways
Non competetitive inhibitors often bind permanentally to the allosteric site - permanentally changing the shape opf the actice site preventing Enzyme substare complexes forming.
Ibubrofen and Aspirin as competitive inhibitors of the enzymes Cyclooxygenase (COX1 & COX2)
