Why are enzymes so important? because they act as a catalyst in the chemical reactions necessary for life within organisms. because they cause decomposition reactions. because they are the building blocks of proteins. because they are the building blocks of dna and rna.

Enzymes are so important because they act as a catalyst in the chemical reactions necessary for life within organisms.

Catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms.the reaction starts at a particular temperature and pH and so there is a need of catalyst to enhance the rate of reaction and lower down the energy required for the reaction i.e lowering the threshold  energy .

the answer to your question is b

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
