← Human Body & HealthWhat causes reduced protein clearance during neural aging?
A)Increased lysosome acidification efficiency
B)Enhanced proteasome subunit expression levels
C)Impaired macroautophagy flux in neurons✓
D)Elevated chaperone-mediated autophagy activity
💡 Explanation
Impaired macroautophagy flux causes reduced protein clearance during aging because it reduces the cell's ability to degrade aggregated proteins. Therefore, autophagy defects lead to neurodegeneration, rather than increased lysosome acidification which would enhance protein degradation.
