Question

Consider the following image depicting enzyme behavior.  Which of the following correctly characterizes the components of this model?
A) A - enzyme, B - substrate, C - active site, D - E-S complex 
B) A - substrate, B - active site, C - enzyme, D - E-S complex 
C) A - active site, B - substrate, C - E-S complex, D - enzyme 
D) A - substrate, B - enzyme, D - E-S complex, D - active site

Quizplus · Accepted Answer

A - substrate, B - active site, C - enzyme, D - E-S complex. The image depicts the formation of an enzyme-substrate complex (E-S complex) through the binding of the substrate to the enzyme's active site. Therefore, the best choice is B where A represents the substrate, B represents the enzyme's active site, C represents the enzyme, and D represents the E-S complex.
