This model supports that a specific substrate(key) can be inserted into a particular enzyme(lock). Means that enzyme are subtrate-specific.
Explanation:
Lock and Key Model:
Emil Fischer proposed this model in
- As one specific key can open only a specific lock, just like that a specific enzyme can convert only one particular substrate into product(s).
- This model supports that an active site is a rigid structure.
- And active site play a role of template only. So, there is no modification in the active site before, during or after the reaction.
)
This model was further improved by Koshland and he named the new model as "Induced fit model" which was practically more accepted.
Hope it helps...
