Enzymes - Chapter 6 Flashcards
1
Q
What do oxidoreductases do?
A
These enzymes catalyze oxidation-reduction reactions and transfer electrons between molecules.
2
Q
What do transferases do?
A
These enzymes transfer functional groups between molecules.
3
Q
What do hydrolases do?
A
These enzymes cleave molecules via the addition of water.
4
Q
What do lyases do?
A
These enzymes add functional groups to a double bond or removes them to form a double bond.
5
Q
What do isomerases do?
A
These enzymes move functional groups within a molecule.
6
Q
What do ligases do?
A
These enzymes join 2 molecules in reactions powered by ATP hydrolysis.
7
Q
What are apoenzymes?
A
enzymes without their cofactors
8
Q
What are holoenzymes?
A
catalytically functional enzymes with their cofactors
9
Q
What are the 2 kinds of cofactors?
A
- Coenzymes (small biological molecules)
- Metals
