This flashcard outlines three key arguments that falsified the Davson-Danielli model of the cell membrane. These include the insolubility of membrane proteins, protein mobility shown by fluorescent antibody tagging, and the rough surface revealed by freeze-fracturing.
This flashcard outlines three key arguments that falsified the Davson-Danielli model of the cell membrane. These arguments include the insolubility of membrane proteins in water, the mobility of proteins shown by fluorescent antibody tagging, and the appearance of the membrane surface in freeze-fracture electron micrographs.
| Front | 3 falsifications of davson danielli model |
|---|---|
| Back | 1. membrane proteins insoluble in water, would not form uniform and continuous layer around membrane 2. fluorescent antibody tagging showed protein's mobility 3. freeze fracturing split the membrane and revealed irregular rough surfaces (transmembrane proteins) |
