Enzymes are regarded as catalysts because they:

Are consumed in the process
Change the products of reactions
Speed the rate of metabolic reactions without being consumed
Slow down metabolic reactions

The correct answer is: Speed the rate of metabolic reactions without being consumed

Enzymes are proteins that act as catalysts in biological reactions. This means that they speed up the rate of reactions without being consumed or altered themselves. Option A is incorrect because enzymes are not consumed in the process of catalyzing reactions - they can be used repeatedly. Option B is incorrect because enzymes do not change the products of reactions, they only facilitate their production. Option D is incorrect because enzymes do not slow down metabolic reactions, they actually accelerate them. Therefore, option C is the correct answer because it accurately describes the role of enzymes as catalysts.
