What is the reason why the transition state of a catalyzed reaction is lower has lower energy compared to an uncatalyzed reaction?
A. because enzymes only work at low temperatures
B. because of favorable interactions with the substrate
C. because of enthalpic interactions between the enzyme and the transition state
D. A and B
a) How do enzymes catalyze (increase the rate of) reactions? b) What does it mean that
enzymes are “substrate specific”? c) How are they usually name
compare the state of an enzyme active site at a low substrate concentration and at a high substrate concentration. How does this affect the rate of the reaction?
