Nadia Mohamad Rom AT1 Practical investigation An investigation in to the effect of temperature on the release of pigment from beet root tissue Introduction and Hypothesis I think that the increase of the temperature on the beetroot will affect the diffusion of the colour dye in the beetroot. The colour dye is held together by the membrane structure and this maintains the red rich colour in the beetroot. I believe that with the increase of temperature applied onto the plasma membrane, the structure of the membrane will become damaged and the membranes of the protein will eventually denature. Scientists know that cell membrane have the following general characteristics: - * 40% Lipid * 0 - 10% carbohydrate (as prosthetic groups) * 50 - 60% protein. You can see from above that proteins are major constituents of membranes. In membranes there are intrinsic and extrinsic proteins. Intrinsic membrane proteins completely pass through the lipid layers....
