Do Enzymes Affect Chemical Equilibrium? Understanding Enzyme Action in Catalysis
The correct answer is (1) disturbing the equilibrium of the chemical reaction. Enzymes are biological catalysts—they speed up reactions and alter the pathway (lower activation energy), but do not change the reaction’s […]
