Question

Alzheimer's disease is characterized by an accumulation of proteins such as beta-amyloid protein in the cells. Beta-amyloid mRNA levels do not increase in patients with Alzheimer's disease. Explain how beta-amyloid protein levels increase in these patients' Multiple Choice The beta-amyloid proteins have a decreased rate of synthesis. The beta-amyloid proteins are not broken down and recycled. The beta-amyloid proteins have an increased rate of synthesis. The beta-amyloid proteins are secreted from the cell.

Explanation / Answer

In Alzheimer's disease beta amyloid is secreted out of the cell and gets accumulated as aggregate (clump).This causes neuronal dysfunction and associated symptoms.

Hence 4th option is correct.
