Chemical Reaction Quote by Brett Osborn
““Yes. There are a variety of reasons that we as humans age, one of which is oxidant stress from free radical formation. Known as the Free Radical Theory of Aging, this explanation was first proposed by Denham Harman in the 1950s. Other theories include unchecked inflammation, glycation, cell membrane and DNA damage. Interestingly, they are interrelated as I will explain. Every cell in our body requires energy for a variety of processes. The production of such cellular energy or ATP (adenosine triphosphate) is occurring at the molecular level, unbeknownst to you, billions of times per second, in cellular structures known as mitochondria. Through a complex series of chemical reactions, electrons are ultimately transferred to oxygen, driving the formation of ATP molecules. No oxygen, no electron receptor, death ensues. (Note: Cyanide poisons this so-called “electron transport chain” often times resulting in death.) This process of ATP generation is imperfect.””
