The mechanics in the obtaining of energy in bacteria is a process in which we are compelled to study.
Bacteria gather all of their energy through a process called cellular energy this is governed by what is called electronic-transfer reactions. This is astounding!
In the microscopic bacteria start out with collecting their energy by observing it then, by using electronic-transfer reactions they send electrons from an organic or an inorganic donor molecule that will arrive at a acceptor. Once the energy, in the form of electrons, are on their way to the acceptor they get seated in ATP.
And, we have talked about ATP. For a recap of that refer to Logy-Bacteria – Energy – Part 1
