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\' cells. The beta-amyloid proteins have a decreased rate of synthesis. The beta-amyloid proteins are not broken down and recycled. The beta-amyloid proteins are secreted from the cell. The beta-amyloid proteins have an increased rate of synthesis.

Solution

Alzheimer\'s disease is characterised by increase level of beta amyloid protein in cell. In healthy patient these proteins are broken down and elliminated.

Hence most perfect answer for your question is 2nd one i.e. BETA AMYLOID PROTEIN ARE NOT BREAKDOWN AND RECYLCED.
