WebJul 4, 2024 · Enzymes are specific to substrates as they have an active site which only allow certain substrates to bind to the active site. This is due to the shape of the active site and any other substrates cannot bind to the active site. there is a model which is well known in the biology field of the lock and key model. WebJun 19, 2013 · The enzyme binds to the cellulose substrate (S) first by either the CBM or CD. Next, an individual cellulose chain is decrystallized from the surface and slides into the enzyme active site through various nonproductive enzyme–substrate complexes (E-Sn).
