Which one of the following statements is true of enzyme catalysts?

#SCPH05 I Biotechnology

  1. They bind to substrates, but are never covalently attached to substrate or product.

  2. They increase the equilibrium constant for a reaction, thus favoring product formation.

  3. They increase the stability of the product of a desired reaction by allowing ionizations, resonance, and isomerizations not normally available to substrates.

  4. They lower the activation energy for the conversion of substrate to product.
