Question

Quizplus · Accepted Answer

A catalyst that is in a different phase from the reactants and products is called a heterogeneous catalyst. A homogeneous catalyst is in the same phase as the reactants and products, and an enzyme-type catalyst refers specifically to catalysts that are biological in nature (such as enzymes). Protein and exogenous do not specifically refer to catalysts and are not relevant to this question.
