Question

Quizplus · Accepted Answer

The cytochrome oxidase system uses ions such as copper and iron to facilitate electron transfer during aerobic respiration. Urease (A) requires the presence of the enzyme to catalyze the hydrolysis of urea into ammonia and carbon dioxide. Pepsin (B) is a digestive enzyme that breaks down proteins into smaller peptides. Creatine kinase (C) catalyzes the transfer of a phosphate group from phosphocreatine to ADP, producing ATP. Alcohol dehydrogenase (D) converts alcohol to acetaldehyde. None of these processes directly involve ion transport or electron transfer through a membrane-bound system.
