Enzymes: Proteins/Catalysts Flashcards
1
Q
What are proteins made up of?
A
long chains of amino acids
2
Q
How are the long chains folded?
A
- produce specific shapes (active site)
- different shapes have different functions
3
Q
What are the functions of proteins?
A
- structural components
- antibodies
- hormones
- catalysts
4
Q
What do catalysts do?
A
increase the rate of a chemical reaction
5
Q
What are biological catalysts?
A
enzymes
6
Q
What is the area where specific substrates fit into?
A
active site
7
Q
What does an enzyme and a substrate form?
A
enzyme substrate complex
8
Q
What can enzymes do?
A
- build large molecules from smaller ones
- change one molecule into another
- break down large molecules into smaller ones
9
Q
How do enzymes work best?
A
- warm temperature
- correct pH
10
Q
What happens to enzymes if the temperature is too hot?
A
- denature
- active site changed shape
