Which of the following increases the reaction rate? a. adding a catalyst to the reaction mixture b. increasing the size of solid reactant particles c. lowering the pressure of gaseous reactants d. adding an inert gas to the reaction mixture

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
