Which statement best describes how a catalyst can speed up a chemical reaction?
o
o
the catalyst makes lower energy pathways available
the catalyst increases the concentration of products
the catalyst binds to enzymes to release substrates
the catalyst increases the concentration of reactants,
o

The correct answer is The catalyst makes lower energy pathways available.

Explanation:

Catalyst are chemical or biochemical compounds the increases the rate of a chemical reaction but itself remain unchanged.

  Catalyst exerts this affect by lowering the activation energy of the reactant but do not have any effect in the equilibrium of that reaction.

 Thus catalyst speeds up the rate of chemical reaction.
