http://chemistry.elmhurst.edu/vchembook/568denaturation.html WebDec 18, 2016 · The specificity of enzymes ensures that only a specific substrate can form the enzyme-substrate-complex structure, induce a conformational change in an enzyme, and receive the energy needed to catalyze a specific reaction. This helps cells ensure that their enzymes are not randomly conducting reactions throughout the cell. WebDenaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process.
