The basic steps of an enzyme-catalyzed reaction are
A)substrate and product combine, forming an S-P complex. The reaction occurs, enzymes are released, and the unchanged substrate is released and recycled.
B)substrate and enzyme combine, forming an E-S complex. The reaction occurs, products are released, and the unchanged enzyme is released and recycled.
C)substrate, enzyme, and product combine, forming an S-E-P complex. The reaction occurs, products are released, and the unchanged enzyme is released and recycled.
D)enzyme and product combine, forming an E-P complex. The reaction reverses, enzymes are released, and the unchanged substrate is released and recycled.

Question

Quizplus · Accepted Answer

The correct sequence of steps in an enzyme-catalyzed reaction is substrate and enzyme combining to form an E-S complex, reaction occurring to form products, and then unchanged enzyme being released and recycled. This is described by choice B. The other choices are not accurate representations of enzymatic reactions.
