A researcher observes that a reaction occurs 1000 times faster in the presence of a specific protein.
What is the most likely mechanism by which this protein accelerates the reaction?
- It increases the temperature of the local microenvironment to increase collision frequency.
- It provides an alternative reaction pathway with a lower activation energy.
- It decreases the reaction enthalpy Δ H to make the reaction more exothermic.
- It shifts the equilibrium constant K toward the products.
