Why does alcohol effect cell membrane permeability?

Answer 1

The greater the alchohol concentration then the more Osmosis/ diffusion will occur. The acctual membrane permiability will remain the same. Dont trust this too much as this varys wildly depending on the experiment your doing. Good luck with the ISA!

Answer 2

alcohol enters all cells as do solvents simply because both are thinner than water and are more susceptible to osmotic pressure for the same reason' and does not an homolgize with lipids' it is toxic to all cells' and causes mis-transcriptions of which p55 protein cannot rectify' so can cause apoptosis and malignant mutations' and create new viruses especially when homologizes with hormones and bacteria toxins such as pylori vac A example; herpes' HIV etc etc' alcohol damages electrical conductance and causes neurons to mis-signal' which leads to high blood pressure; and brain deterioration' such as Alzheimer's' etc' it is well known to down regulate calcium+2 ions' note; well alcohol can be produced in the body without consuming Alcoholic Beverages; FACT;

Answer 3

You have to be careful with this question, alcohol does not affect the permeability of the cell membrane. However alcohol increaces the rate of diffusion throught the cell membrane.

Answer 2

Alcohol dissolves lipids from cell membrane thus it increases permeability as it can be seen in case of Gram staining .

Answer 4

Alcohol affects the production of adh by the petuitary gland, osmotegulation are located on the hypothalamus and when low blood pressure is detected or low water content adh is made. Adh travels to the nephrons and causes the cells to allow more water to return into the body to dilute the blood plasma. By drinking, the body slowly stops making adh and therefor more urin is produced as a result of non permiable collecting tubule walls not repbsorbing water.

Answer 5

Ethanol is a solvent so will affect the permebility of the cell. It will break down the phospholipid bilayer and will denature the protein by breakin the hydrogen bonds,

Answer 6

The cell membrane is mainly composed of phospholipids, which can easily be dissolved by alcohol. This results to an increase in the permeability of the cell membrane.

Answer 7

If memb. Are permeable then all cell macromolicules are goese outside and conc. Not maintaind

Answer 8
