A variety of factors influence enzyme activity. Substances that bind to the enzyme and interfere with substrate binding or catalysis are inhibitors. Identify the type of inhibition associated with each of the following descriptions and examples by sorting each item into the appropriate bin. The bins are: irriversible inhibition, compenitive inhibition, mixed inhibition The phrases to sort are: -Tamiflu, a transition state analog, reversibly binds to neuraminidase - Inhibitor may perminantely modify an enzyme -DIPF permanently modifies the hydroxyl group...
