WebMar 5, 2024 · Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site (Figurebelow). By binding reactants at the active site, enzymes also position reactants correctly, so they do not have to overcome intermolecular forces that would otherwise push them apart. WebMay 2, 2024 · $\begingroup$ I wouldn't say "can bind with more substrate" I would say "binds substrate more strongly" - the answers to your other two questions are yes - affinity is a function of the structure of the enzyme (as well as the shape/structure of the ligand), and yes a difference in affinities in two species indicates there is a difference in amino acids … WebJun 8, 2024 · As the enzyme and substrate come together, their interaction causes a mild shift in the enzyme’s structure that confirms an ideal binding arrangement between the … green acres thousand oaks
