Quizplus · Accepted Answer

Lipofuscin is a type of cellular waste product that accumulates in cells as we age, particularly in the brain, heart, and liver. SOD (superoxide dismutase) is an enzyme that helps to neutralize free radicals, which are another type of waste product that can cause cellular damage but are not necessarily linked to senescence. Collagen is a structural protein that is not considered a waste product.
