Investigate the Effect of Temperature on Cell Membranes and Membrane buildingIf you read a recipe for cooked beet it will usually barrackthat you acceptt remove the outer skin of the beet and dont cut offal the stalk and root if you involve to avoid getting lots of red dye inthe cookery water. Beetroot contains red pigments called betalains,located within the mobile phone vacuole. Normally the pigments kindlet passthrough membranes but they leak out when the beetroot is cooked.Aim The aim of this practical is to use beetroot to examine the core of the temperature on cell membranes and relate the effectsobserved to membrane structure. To conk out correctly a cell needs tobe able to adjudge transport crosswise the partially permeable cellmembrane.Theory To commiserate how the red pigment leaks out of the beetrootit is essential that we netherstand the molecular Structure of a plasmamembrane.A membrane is a phospholipid bilayer. This style that it has twolayers of molec ules called phospholipids. Each of these phospholipidmoleculeshas two parts A head that will sashay with water but not with fat (i.e. it is deliquescent) Two tails that will pleat with fat but not with water (i.e. they be hydrophobic).In the phospholipid bilayer, the hydrophilic heads are always on theoutside of the membrane. The hydrophobic tails are always on the inside of the membrane. Alone, this arrangement of phospholipids would forma restriction to water and to water-soluble substances. thus far, othermolecules are scattered among the phospholipids. These include lipids(including cholesterol in the membranes of animals), proteins andpolysaccharides. The proteins in membranes are of special interest tous. This is because they have a number of important functions. Proteins function as Carriers for water-soluble molecules (such as glucose) impart for ions (such as sodium and chloride ions) Pumps, which use energy to move water-soluble molecules and ions Receptors, which enable hormones and nerve transmitters to bind to specific cells Recognition sites, which identify a cell as being of a particular type Enzymes, which speed up chemical reactions at the edge of the membraneThe ways that substances move across cell membrane are1.

This might be due tosources of error in my experiment.Experiments - I have successfully gained my results that back myhypothesis. However the results have limitations and some sources oferror. The sizing of the beetroot is essential. In my experiment I useda formula and bobsleigh bore to measure out the same size beetroot. The corkborer was a a good aid as it ensured that the beetroot had the samediameter. However using a ruler could present potential error. Due tothe surface area to volume ratio.As the test tubes were interpreted out of the water bath and placed the inthe colorimeter the temp reduced by a few degrees. This small errorcould of budge the results by 0.5 percent inaccuracy. This is becauseof insufficient equipment.I understand this experiment is unless on a small scale but to gain bankrupt results each test tube going up in 10 degrees Celsius so we cantell the point of denaturing more accurately, however I feel that I myexperiment showed breath of how a membrane functions under temperaturechange.
