Descriptions of enzyme mechanisms often contain the terms intermediate, transition state, and transition state analogue. The terms intermediate and transition state both describe chemical species along the reaction pathway, but there are important distinctions between the two. Transition state analogues are often used in enzyme mechanism studies. Match each phrase to the term that it describes. a. compound designed to mimic the structure of a transition state
b. examples include ES ( enzyme-substrate complex) and EP (enzyme-product complex)
c. some are stable enough to be detected and structurally characterized
d. contains partially formed and partially broken bonds
e. compound designed to mimic the structure of a transition state
f. some are stable enough to be detected and structurally characterized
g. hypothetical max energy species of a rxn pathway; does not have a finite lifetime

1. Intermediate
