Created page with "==Key Stage 3== ===Meaning=== The '''lock and key model''' is a way of explaining why enzymes only work on certain substrates. ===About The Lock and Key Model===..."

New page

==Key Stage 3==
===Meaning===
The '''lock and key model''' is a way of [[explain]]ing why [[enzyme]]s only work on certain [[substrate]]s.

===About The Lock and Key Model===
: The '''lock and key model''' proposes that an [[enzyme]] is a like lock and a [[substrate]] is like a key as only one key can fit a lock, just as only one [[substrate]] can fit into the [[Active Side|active site]] of an [[enzyme]].
