People who have Alzheimer's disease experience an increasing loss of brain function and cognition over time. Alzheimer's is characterized by a buildup of abnormal protein fragments that damage brain cells. Recently scientists have discovered an enzyme, BACE2, that decreases these abnormal protein fragments in the brain of a person with Alzheimer's disease. Which statement explains how BACE2 most likely works? BACE2 is a reactant that combines with the abnormal protein fragments. BACE2 speeds up the reaction that breaks down the abnormal protein fragments. BACE2 molecules link several abnormal protein fragments together, forming a complete protein. BACE2 breaks down into smaller pieces that react with the abnormal protein fragments forming more complex molecules.
