Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
