In 1836, he discovered pepsin, the first enzyme to be isolated from animal tissue, and, before the work of Pasteur, he showed the role of yeast cells in producing fermentation.
This physiologist first showed that an egg is a single cell that eventually develops into a complex organism, and he also coined the term "metabolism." In 1836, he discovered pepsin, the first enzyme to be isolated from animal tissue, and, before the work of Pasteur, he showed the role of yeast cells in producing fermentation. His most important work culminated in the 1839 Microscopical Researches on the Similarity in the Structure and Growth of Animals and Plants, where he concluded that all organisms consist entirely of cells and that the life of each cell is subordinated to that of the organism. FTP, identify this scientist who also discovered the eponymous satellite cells that envelop many peripheral nerve axons.
