What is a substrate?
1 Answer
A substrate is something that enzyme needs in order to perform its catalytic activity.
Explanation:
But the main point is that, 'An enzyme will bind to a specific substrate to transform it into products'. Thus, any substrate can't activate the active site of enzyme but a specific one. This means enzymes are highly specific in their actions. That's the reason that a single enzyme can catalyze only single chemical reaction or group of related reactions.
Relationship between enzyme and substrate:
Following theories are proposed to grasp the relationship of enzyme and substrate.
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).
- An active site is a rigid structure.
- And active play a role of template only. So, there is no modification in the active site before, during or after the reaction.
