Urease Is an Enzyme That Catalyzes the Decomposition of Urea $k = A \exp \left( - \frac { E _ { a } } { R T } \right)$

question 7

Short Answer

Urease is an enzyme that catalyzes the decomposition of urea to ammonia and carbon dioxide. The rate constant for the uncatalyzed reaction is 4.0* 10^-11/s at 22°C. Urease increases the rate constant to a value of 8.0 *10^-5/s. Use the Arrhenius equation, which is given below, to determine the difference in the activation energies E_uncatalyzed - E_catalyzed. (R = 8.315 J / (mol K)) $k = A \exp \left( - \frac { E _ { a } } { R T } \right)$

Classical Conditioning

A learning process that occurs when two stimuli are repeatedly paired: a response that is at first elicited by the second stimulus is eventually elicited by the first stimulus alone.

Idiosyncratic Phobias

Unique and unusual fears that are specific to an individual, differing significantly from common phobias.
