D) cross-linking of glucose theory of aging.

Question

Quizplus · Accepted Answer

The free radical theory of aging proposes that aging results from the accumulation of damage caused by free radicals, which are oxygen-containing molecules that can damage other molecules in the body, including DNA and proteins. The mitochondrial theory of aging is related to the free radical theory, but specifically focuses on damage to the mitochondria, which generate energy for the cell. The genetic theory of aging proposes that aging is genetically programmed, and therefore inevitable. The immunity theory of aging proposes that aging is linked to a decline in the functioning of the immune system. The cross-linking of glucose theory proposes that aging results from the accumulation of cross-linked proteins in the body, which can result in a loss of elasticity and function in tissues.
