enzymes Flashcards
1
Q
What is a catabolic reaction?
A
A breakdown reaction
2
Q
What is an anabolic reaction?
A
A building reaction
3
Q
In order to catalyse a reaction, the enzyme and substrate
A
must collide to form a substrate complex
4
Q
The reaction takes place in
A
the active site
5
Q
What is the lock and key model of enzyme action?
A
this
6
Q
What is the induced fit model of enzyme action
A
7
Q
What is a prosthetic group and coenzyme
A
Types of cofactor (non-protein substance), prosthetic groups are permanent while coenzymes are not but necessary for enzyme action
8
Q
Temperature
A
More kinetic energy, more collisions, higher rate of reaction, until denatured active site, rate of reaction goes down
9
Q
4 types of immobilisation
A
Adsorption
Entrapment
Encapsulatin
Crosslinkage
10
Q
Inhibition
A
Competitive and non-competitive
