Question 1

What is an enzyme?

Answer 1

Proteins that act as biological catalyst, increasing reaction rate of biological processes without being used up in the process

Question 2

What does catalytic activity of an enzyme rely on?

Answer 2

On its tertiary structure, a change in the three-dimensional shape denature the enzyme

Question 3

Where does the selectivity of enzymes come from?

Answer 3

From their shape and functional group in active site, allowing them to only been with certain substrates

Question 4

What are the four types of active site and substrate interactions?

Answer 4

Dispersion forces interaction
Ion dipole
Hydrogen bonding
Ionic interactions

Question 5

What can denature an enzyme?

Answer 5

Increase temperature
A change in PH
The addition of heavy metal ions

Question 6

How can the RF value be determined?

Answer 6

Distance from origin by component divided by the distance, moved by solvent from the origin
