<em>They mostly occur at boundaries between tectonic plates. They can also be found by a belt called the "Ring of Fire" that encircles the Pacific Ocean. Volcanoes like that can be formed in Hawaii Islands in the part of the interior plate. These areas are known for being called the "hot spots." </em>

Answer:
Enzymes are homogenous, thermolabile,biological catalyst that increases the reaction rate of a chemical reaction.
Explanation:
Enzymes are used as catalyst in many biochemical reactions.Enzymes basically interact in a complementary fashion with the transition state of the reaction thus helping to decrease the energy barrier called activation energy.Thus enzymes helps to stimulate the velocity of biochemical reaction.
It is very important point to note that enzymes do not affect the reaction equilibrium.
Because of the characteristic of catalyst. The catalyst is used to accelerate the reaction rate and will not participate the reaction itself. The catalyst can not be changed or consumed during the reaction. So it does not need to be replaced.
