““We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw ( Pasteur ), or as lock and key ( E. Fischer ).””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The cell’s chemistry can be seen as specific side‑chains that bind nutrients, similar to lock‑and‑key mechanisms.
In simple terms: Cells use specific chemical groups to capture food.
