The theory notes that as one ages, the collagen loses some of its elasticity and there is a hardening of the arteries of the circulatory system.

The Cross-Linkage theory

Explanation:

The theory was referred as glycosylation theory (glucose binds to proteins) of ageing was purposed in 1942 by Johan Bajorksten.

The cross-linkage theory of ageing explains how a person grow old and what physiological changes occurs in his body. According to cross-linkage theory as the name indicates ageing results from inter and interamoleculer covalent linkages between molecules. Specifically, these molecules include glucose and proteins. The glucose binds to protein in the aerobic condition. These interactions between molecules change the biological and chemical properties of cells and consequently produces the whole organ dysfunctions. The most common dysfunctions are

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
