Question

Quizplus · Accepted Answer

A catalyst is a substance that speeds up the rate of a reaction without being consumed or altered in the process. It works by providing an alternative pathway with a lower activation energy, allowing the reaction to proceed more easily. The other choices are not accurate: an enhancer is not a scientific term, a substrate is a molecule acted upon by enzymes but does not fit the definition of a catalyst, and a co-enzyme is a type of molecule that helps enzymes carry out their function but is not a catalyst on its own. A reactant is a substance that participates in a chemical reaction but is not necessarily a catalyst.
