Enzymes Flashcards
1
Q
What are enzymes
A
Biological catalysts
2
Q
What is a catalyst?
A
A substance which increases the speed of a reaction without being changed or used up in the reaction
3
Q
What is an active site
A
A specific region on an enzyme where substrate molecules bind together to undergo a chemical reaction
4
Q
How many reactions do enzymes catalyse for?
A
One specific reaction
5
Q
Why do enzymes only catalyse one specific reaction
A
Because for the enzyme to work the substrate has to fit in the active site
6
Q
Explain the Locke and key method
A
It explains how a substrate fits into an active site
7
Q
Factors that effect the rate of enzyme reactions
A
Temperature, ph
