Weak interactions between enzyme and substrate are optimized in the transition state

Enzymes catalysis Enzyme catalyzed chemical reactions via both non-covalent and covalent interactions. Transient chemical reactions (i.e., covalent interactions) often occur between substrates and functional groups in the active sites of enzymes, thus providing an alternative reaction path.
