Question

cellular aging might involve all of the following processes except one. o damage by free radicals. o autoimmune responses. o irreversible cross - links between glucose and proteins. o lengthening of telomeres.

Explanation:

Telomeres shorten with each cell - division. Cellular aging is related to irreversible cross - links between glucose and proteins (glycation), autoimmune responses, and damage by free radicals. But telomere lengthening does not occur during normal cellular aging.

Answer:

A. Lengthening of telomeres.
