Enzymes Flashcards
1
Q
What is maximal velocity, Vmax?
A
Maximal rate when all enzyme active sites saturated with substrate
2
Q
What is Km?
A
Substrate concentration that gives half the maximal velocity
Low Km = high affinity of enzyme for substrate
3
Q
What do allosteric activators do?
A
Increase proportion of enzyme in R state = high affinity = higher rate = graph shifts left
