Heme – “vital for life”, but too much and it is toxic and causes cancer, diseases, and aging.
“Manufacturing it is therefore an absolutely essential biological process, but this must be tightly controlled.
…This is yet another demonstration of the fact that cells are far from simple. Here we see they are logistics experts, employing complex systems of checks and balances. In this case, it involves perfectly gauging the supply and demand of this absolutely essential but potentially deadly ‘commodity’—heme.
…Did you notice the language used by the scientists—“highly controlled”, “exquisite control”, “signaling and regulation”? It is the language of design.
…How could such superlative control have evolved step-by-tiny-step, without any guiding hand? And with no plan or purpose, as advocates of evolution must insist? There are no less than eight enzymatic steps in the complex chemical pathway for the making of heme, some of which occur in your marvellous mitochondria, and some within the cytoplasm of your cells. Heme manufacture is anything but simple!”
