Enzymes

HideShow resource information
What are enzymes?
Enzymes are soluble protein molecules that can speed up chemical reactions in cells.
1 of 5
Where can enzymes speed up chemical reactions?
DNA replication,Protein synthesis and Digestion
2 of 5
How do enzymes react in different temperatures?
At low temperatures, enzyme reactions are slow. They speed up as the temperature rises until an optimum temperature is reached. After this point the reaction will slow down and eventually stop.They work best at temperatures around 40.
3 of 5
Where do enzymes work fastest?
Most enzymes work fastest in neutral conditions.

What happens to an enzyme when they are over heated?
Increasing the temperature to 60°C will cause a permanent change to the shape of the active site. This is why enzymes stop working when they are heated. We say they have become denatured.
