1
Q
What are enzymes?
A
Proteins that function as biological catalysts
2
Q
What are the main characteristics of enzymes?
A
Not alive, 3D, specific, all chemical reactions depend on them
3
Q
What is a biological catalyst?
A
A substance that speeds up chemical reactions in organisms without being used up.
4
Q
What is the active site in an enzyme?
A
The site on the enzyme where the reaction takes place.
5
Q
Explain what happens in the active site referring to the substrate and product formation.
A
A substrate needs to have a complementary shape to the enzyme in order for it to react.
6
Q
What is meant by the term ‘optimum’ temperature or pH?
A
Particular temperatures or pH levels where enzymes work best at (rate of reaction is at its peak)
7
Q
Which graph shows the effect of temp and pH
A
