The key difference between the two is that inhibition binds to and blocks the active site. The binding of an inhibitor can stop a substrate from entering into enzyme's active site. Inhibitors can bind both reversibly and irreversibly.

Problem 36.16 11 of 14 > Part A The enzyme fumarase catalyzes the hydrolysis of fumarate: Fumarate(aq) + H2O(1) L - malate(aq). The turnover number for this enzyme is 2.5 x 10 s-4, and the Michaelis constant is 4.2 x 10" M. What is the rate of fumarate conversion if the initial enzyme concentration is 1.0x10-6 M and the fumarate concentration is 1.0x10-4 M ? Express your answer with the appropriate units. Ro = Value...

Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
