Enzymes Flashcards
0
Q
Competitive inhibitor
A
Binds to active site, can be overcome by adding more substrate, increases Km
1
Q
Enzymes
A
- Lower activation energy of rxn
- Increase rate of rxn
- Do not affect overall delta g or delta h of rxn
- Not changed or consumed in course of rxn
2
Q
Non competitive inhibitor
A
Binds to site other than active site, cannot be overcome by adding more substrate, Km remains unchanged but Vmax decreases
3
Q
Pancreatic enzymes work optimally in
A
Alkaline conditions of small intestine
4
Q
Apoenzyme
A
An enzyme devoid of its necessary cofactor and is catalytically inactive
5
Q

A
The active site
6
Q
Holoenzymes
A
Enzymes with cofactors
7
