B) cross-linking theory
C) programmed theory
D) wear-and-tear theory

Question

Which theory of aging would be most useful at explaining why muscle tissue and some arteries get stiffer over time, leading to potentially severe consequences?​
A) ​free radical theory
B) cross-linking theory​
C) ​programmed theory
D) ​wear-and-tear theory

Quizplus · Accepted Answer

The cross-linking theory proposes that aging occurs as a result of the accumulation of advanced glycation end-products (AGEs), which are formed when sugars react with proteins and lipids in the body, causing cross-links to form between them. This process results in the stiffening and loss of elasticity of tissues such as muscle and arteries, leading to potentially severe consequences such as hypertension, heart disease, and stroke.
