You identify an enzyme involved in a cellular reaction.How does the enzyme affect the reaction equilibrium between reactants and products and the time needed to reach equilibrium?
A)It alters the reaction equilibrium and shortens the time needed to reach equilibrium.
B)The reaction equilibrium is unaffected,but it shortens the time needed to reach equilibrium.
C)It alters the reaction equilibrium and lengthens the time needed to reach equilibrium.
D)The reaction equilibrium is unaffected,but it lengthens the time needed to reach equilibrium.

Question

Enzymes do not alter the reaction equilibrium but rather accelerate the rates at which the reaction occurs, which shortens the time needed to reach equilibrium. This is because enzymes lower the activation energy required for the reaction to occur, making it easier for the reactants to convert into products.
