The reduced accumulation of cellular damage and slowed rate of aging seen in calorie restriction are supported by the observation that ______ proteins are up-regulated.

Question

Quizplus · Accepted Answer

Calorie restriction leads to up-regulation of chaperone proteins, which help prevent and repair cellular damage, and therefore contribute to the observed reduced accumulation of damage and slower aging. Regulatory proteins, mitochondrial proteins, and ribosomal proteins may also be affected by calorie restriction, but they do not have as direct a connection to the observed benefits.
