Free BCAAâs are a little different in that they are. directly transported to the bloodstream through the. liver, while some exchange in the intestinal viscera and. go directly to the bloodstream also. Most all amino. acids can be degradated, broken down, in the liver. effectively, with the exception of BCAAâs.
They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs roamed the earth. Without microbes, we couldnât eat or breathe. Without us, theyâd probably be just fine.
A microorganism or microbe is an organism which is too small to be seen by the unaided human eye. They are microscopic. The study of microorganisms is called microbiology. Microorganisms include bacteria, fungi, archaea or protists and viruses.The first four types of microorganisms may be either free-living or parasitic. Viruses, however, always reproduce inside other living things.icroorganisms live almost everywhere on earth where there is liquid water, including hot springs on the ocean floor and deep inside rocks within the earth 's crust. Such habitats are lived in by extremophiles. Microorganisms are critical to nutrient recycling in ecosystems, because they act as decomposers.
