Question

what are the effects of enzymes on chemical reactions? select all of the answers that apply. a. enzymes increase the heat of reaction. b. enzymes decrease the activation energy. c. enzymes increase the rate of the reaction. d. enzymes change the ideal ph for a reaction to proceed. e. enzymes provide a site where reactants can be brought together.

Explanation:

Enzymes are biological catalysts. They lower the activation energy required for a chemical reaction to occur, which in turn increases the rate of the reaction. They also provide a site (active - site) where reactants (substrates) can bind and react. They do not change the heat of reaction or the ideal pH for a reaction to proceed.

Answer:

B. Enzymes decrease the activation energy.
C. Enzymes increase the rate of the reaction.
E. Enzymes provide a site where reactants can be brought together.
