Permeability of Beetroot Cell MembranesAn experiment to inquire how temperature affects thePermeability of beet cell membranesInterpretation of Results 0C20C30C40C55C0.240.280.750.790.220.260.350.410.81From 0C to 30C thither is a inert change magnitude of absorbency which showsthat as the temperature increases it is denaturing the cell wall andcell membrane and allowing the beetroot pigment to leek out into thedistilled water.As soon as the precedent of beetroot is placed into the distilled waterdiffusion occurs naturally, which is the net movement of moleculesfrom a region of high assiduity (beetroot sample) to a region oflow concentration (distilled water).From 40C upwards there is a sudden increase of absorbency, this isbecause the optimum temperature of which enzymes and cells can work atis 37C and as soon as you go above this temperature it will cause theenzymes and cells to modify and cease from working as effectively.Even if you then lower the temperature over again the cell will not regainits original shape.Within the phospholipid bi-layer there are proteins, and theseproteins are made up of polypeptide chains which are conjugated togetherby hydrogen, hydrophobic and peptide bonds. Once the temperature hasincreased above 40C the molecules vibrate so energetically that thesebonds break easily and because creating holes within the cell walland phospholipid bi-layer, and al...
