Cellular Aging from Physiological and Economical Perspectives

Abstract

The study of biological processes and functions of the human body under normal circumstances is known as physiology. Cellular physiology is the study of biophysical and biochemistry processes taking place in a cell. Cells age with time. They all have a certain lifespan after which they die common features that can be observed in an aging cell include damaged protein and organelles accumulation even when there is the absence of mutation. Many physiological changes are experienced as cell ages, resulting in the deterioration of normal cell functioning. Examples of such changes include: Cells may enlarge and are unable to multiply or divide, fats and pigments may get deposited in some cells, and some cells may function abnormally, while others may start functioning in the right manner. Any organism that is multicellular and receives energy from the sun can only live for a specific time. As the cellular organism ages, it losses its efficiency and after sometime it might end up dying. Many biologists studying the evolution of organisms deny that aging is genetically caused but rather takes place after natural selection requirements are fulfilled by the organisms. After an organism has had off-springs, it ages with time and eventually dies; however, recent research has shown that genetic components also contribute to aging.
