The accumulative waste theory of aging, also known as the waste accumulation or garbage accumulation theory of aging, proposes that molecules damaged by oxidation and their by products (e.g., aged collagen, damaged enzymes), and damaged mitochondria (organelles responsible for cellular energy production) accumulate in postmitotic (non dividing cells) causing dysfunction, toxicity, aging, and cell death (see Error Catastrophe Theory of Aging).
There are several mechanisms by which garbage accumulation affects cells. (more…)
