Enzymes Flashcards
What are reactions controlled by?
Enzymes
What is an enzyme?
Large proteins
What do enzymes do?
Speeds up reactions
What is another word for an enzyme?
A catalyst
What is a catalyst
A substance which increase the speed of a reaction without it being changed or used up
What does every enzyme have?
An active site
What does the substance in the reaction have to do?
Fit in the active site for the enzyme to work
How does the temperature effect rate of reaction?
The higher it is the faster the reaction will happen
What happens if the enzyme gets to hot?
Some bonds break
How do enzymes become denatured?
When the active site won’t fit anymore due to the bonds being broken
What is the optimum temperature?
The temperature enzymes work best at
How does the PH effect the rate of reaction?
If it is to high or to low it effects the bonds
What is a optimum PH
A PH all enzymes work best at
