as temperature in the environment increases question 3 options: a) the enzyme-substrate complex becomes permanent, and all product formation stops. b) there is decreased kinetic energy in the enzyme and increased kinetic energy in the substrate so product formation slows down. c) there is increased kinetic energy in the enzyme but not in the substrate, so product formation occurs at a steady rate. d) there is increased kinetic energy in both the enzyme and substrate, resulting in more frequent collisions with increased energy, and therefore product formation increases.
