(6 cards)
1
Q
What does enzyme specificity mean?
A
Each enzyme only catalyses a specific reaction.
2
Q
What is enzyme action due to?
A
Its active site.
3
Q
What is the role of the active site in enzyme function?
A
It binds to a specific substrate to catalyse the reaction.
4
Q
What is the lock-and-key model of enzyme action?
A
A model where the substrate fits perfectly into the enzyme’s active site.
5
Q
Why do enzymes have a particular shape?
A
The sequence of amino acids in the protein determines the shape.
6
Q
How do enzymes become denatured?
A
By extreme temperature or pH that changes the shape of the active site.
