WebIntroduction The factors that affect membrane permeability are pH, temperature and concentration of ethanol. Every protein has an optimum pH level, and if it’s distorted then … WebTemperature also affects cell permeability. In order for a living cell to survive, it must have a functioning selectively permeable membrane. [9] If the membrane is distorted it can affect the structure of the proteins and the permeability. [10] Proteins are responsible for the transportation of nutrients in and out of the cell.
