The one experiment that led to the changes to the original cell theory was the experiment that established the existence of single celled organisms and microbes. 1  Comments. 2  Report.
During many cellular reactions, energy changes are due to the movement of electrons (molecules either gain or lose electrons). A molecule that gains an electron is reduced, meaning that there has been a reduction in its positive charge. This gain in electrons is termed reduction.
