Show your workspace.  Your face, both hands, paper, calculator, and notecard should be visible on the video throughout the exam.  You may have to move the computer farther from you to accomplish this.  Items may not be moved in and out of the visible workspace. Showing workspace from Proctorio .png If something goes wrong, email your work and a description of what happened to pcormier@southplainscollege.edu immediately. Failure to follow these guidelines may result in a zero on the exam or being dropped from the course.  I reserve the right to ask you to work any problem on the exam that you answered correctly.

Two curves showing the rate versus substrate concentration are shown below for an enzyme-catalyzed reaction. One curve is for the reaction in the presence of substance X. The other curve is for data in the absence of substance X. Examine the curves and tell which statement below is TRUE for the observation made.

In a certain enzyme-catalyzed reaction the following steps occur:1. A phosphate group on substrate A is transferred to a side chain of an active site residue of the enzyme.2. The dephosphorylated form of substrate A dissociates from the enzyme.3. Substrate B enters the active site and is phosphorylated with simultaneous regeneration of the enzyme in its original form.What kind of kinetic mechanism is described?
