In an enzyme reaction involving one enzyme and one substrate, the rate of the reaction depends on

Question

a. both substrate and enzyme concentrations. b. enzyme concentration. c. the enzyme concentration at first and the substrate concentration later on. d. substrate concentration. e. All of the above f. None of the above

Answer 1

Both the substrate concentration and enzyme concentration determine the rate of reaction. The rate of reaction increases the more enzymes you have. Eventually, reaching saturation if the # of substrate is more than # of enzymes.
