The ethanol would destroy the hydrogen bonds that hold the protein structure.Therefore, with the lipids and proteins destroyed in the cell membrane, the pigment is allowed to escape from the cell due to there being no cell membrane holding substances in the cell.Therefore to conclude that all cell membranes act in this way would be incorrect.

Introduction Biology Coursework Beetroot Hypothesis: To investigate the effect of different concentrations of ethanol on the permeability of beetroot cell membranes.
The European garden flora: Lidocaine administration subcut at the dorsal thoracic region Figure 1 b. There were 3 ratios used: This may also pave the way for the discovery of novel compounds and locally made drugs that can compete in the global market.
Plants supply the phytochemicals of the healing system needed by the body. Phenols have anti-inflammatory and anti-oxidant properties which is the same as the mayana plant.
For the preliminary work, a similar experiment will be investigating the effects of ethanol on the cell membrane of the beetroot instead of temperature.
After completing the temperature investigation, a suitable prediction could be presented by employing the results.
Scientific Knowledge: Transfer across cell membrane structure: There are many ways that ions and molecules are transported across the cell membrane.
By this, the cell must acquire the ions and molecules they need from their surrounding 'extracellular fluid'.
Therefore knowing these effects would help provide a wider knowledge of alcohol on the body's cell membranes and perhaps how to overcome the dangers of drinking.
Preliminary Apparatus: * Beetroot * Corer * Ceramic tile * Scalpel * Tweezers * 10 Test tubes * 10 Boiling tubes * Test tube and boiling tube racks * Measuring cylinder 25cm3 * Colourimeter * Cuvettes * Pipette Preliminary Method: * Using a corer, cut strips of beetroot with the corers at 8mm and ..more.
