http://www.ib.bioninja.com.au/standard-level/topic-2-molecular-biology/25-enzymes/models-of-action.html Witryna2 paź 2024 · The lock-and-key hypothesis assumes that the active site of the enzyme has a specific 3D shape that fits the shape of the substrate exactly. As you have seen, only one substrate or type of substrate will fit the shape of the active site, and this gives the enzyme its specificity.

WitrynaThe matching between an enzyme's active site and the substrate isn’t just like two puzzle pieces fitting together (though scientists once thought it was, in an old model called the “lock-and-key” model).

WitrynaEach enzyme is a particular shape and acts as a lock. Into the enzyme fits certain molecules like a key. The enzyme begins to break down the molecule once this has happened. When the molecule is broken up the enzyme remains the same shape.---picture of this---Enzymes work best at low temperatures (from 5°C-45°C). tech folksWitrynaLock and key model Enzymes are folded into complex shapes that allow smaller molecules to fit into them.
