How does the addition of an enzyme to a chemical reaction affect the initial velocity of the reaction? A) Increases it B) Decreases it C) No effect - Answer A) Increases it Enzymes work by reducing the activation energy barrier of a reaction. Which of the following processes does NOT contribute to this? A) The enzyme binds the substrate specifically and with high affinity. B) Specific amino acid side chains in the active site play a part in the catalytic mechanism. C) The enzyme ensures...
