WebA typical A Level membrane permeability experiment involves investigating the influence of a named variable on the membrane permeability of a vegetable such as beetroot (Beta vulgaris). Common variables to investigate are the effect of solvents or temperature because both of these factors can change the fluidity of the membrane. WebThese changes are reflective of the adaptive mechanisms in response to the acute effects of ethanol. Biophysical studies have shown that ethanol in vitro disorders the membrane and perturbs the fine structural arrangement of the membrane lipids. In the chronic state, these membranes develop resistance to the disordering effects.
