is no better possible mode of communication in cellular biology than that which can be derived from the happy coincidental values of the high availability with concentration control and the response properties of thecalcium ion. Hence, it was an evolutionary requirement that led to a messenger syste...
The notion of a carrier protein as a “ferryboat” binding the substrate at a membrane–solution interface and carrying it to the other side, where the solute is released to the other solution, is inconsistent with current knowledge of the biochemistry and molecular biology of carriers. Neverthele...
