INTRODUCTION
A membrane of the cell is the defensive wall that protects, controls and regulate the amount of ions and water that enter and exit it. While some substances, such as, water, can enter and exit the cell through osmosis, others have to be transported more in some systematic ways, such as, packing or transporting different ions through protein molecule. (Flinders (2016)) Knowing the permeability of a cell membrane helps scientists on many circumstances. One of them is how much concentration of ethanol can damage the cells and how it can be prevented.
From the journal Applied and Environmental Microbiology, it was mentioned that scientists are on an endeavour to find a solution to the global crisis of the declination of the biofuel …show more content…
Next step for the experiment was to decide the quantity of the ethanol, which serves as the independent variable which was decided to be 10%, 50% and 70%. The dependant variable was the absorbance of the treatment because it changed due to the concentration of the treatment, which is the ethanol. The control variable was the time (0 minutes, 15 minutes and 30 minutes) and the amount of ethanol. The group decided to not add any ethanol in the control group. This helps to understand different permeability rate of the Beta Vulgaris and to comparing the speed of each solution to the control …show more content…
This was demonstrated by the increase in the pigmentation of the solution and the measurements that was supplied by the spectrometer. The hypothesis of this experiment was that ‘the greater the concentration of the ethanol, the greater the permeability of the Beta Vulgaris cell membrane’. Overall, the hypothesis was supported by the results although there was some alternation. These results can be used to identify the ability to destroy a cell defence mechanism and find how different kinds of pathogens uses different types of abilities which can help determine the way to prevent it. Some similar studies have been conducted to find how the ethanol can harm eukaryotic cells and prokaryotic cells. One of the studies shows that the increase in the ethanol concentration effects and decreases the electric polarizability of E. coil K12. This reference shows that other experiments are conducted to understand the ability of different cells to withstand against harmful material such as
