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.

Solution

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.
