Why are carbon and oxygen so ubiquitous in living organisms
To be useful for life atoms need two somewhat opposite characteristics; they need to be reactive enough to be readily changed when needed, but not so reactive they degrade by themselves e.g with moisture. Carbon fills that role perfectly. Carbon based molecules will on average hang about a long t…
The Short Answer
To be useful for life atoms need two somewhat opposite characteristics; they need to be reactive enough to be readily changed when needed, but not so reactive they degrade by themselves e.g with moisture. Carbon fills that role perfectly. Carbon based molecules will on average hang about a long time, but when called upon can be manipulated by say enzymes to change. Lead based compounds could stand in for carbon in some instances, but the bonds with other atoms are too weak and wouldnt last for the time needed. Carbon forms strong bonds with hydrogen, oxygen, and nitrogen, which is why they are also widely found in life.
