The Effect of Temperature on the Cell Membranes of Beetroot Cells

Influence of temperature on cell membrane of beat root cell device · Core size 4 · White tile · Beat route · Automatic water bath · Isolation knife · Thermometer · Stopwatch method · First take white tile and core. The root of the beat is collected by pressing the coring rod on the beat route and deleting it. The cylinder remains in the koala - push out with the tip of the pencil. • Collect three cylinders and cut them into 6 3 cm cylinders with a spacer knife.

& Lt; Tab / & gt; This is due to the structure of the cell surface membrane. It consists of a lipid bilayer with protein carrier molecules. When the cell membrane controls permeability, the temperature effect on the protein carrier will alter the permeability of the beet root cell membrane. At low temperatures, the kinetic energy of the dye molecule is low, so movement to and from the cell is reduced. As the temperature rises, the molecule acquires kinetic energy, so the transport across the membrane will be faster and there will be more pigment loss. The maximum speed is about 40 ° C. Carrier proteins begin to lose their shape and therefore do not function properly. This is why proteins lose more pigment and they can not control substances entering and leaving cells.

There are other ways to study the factors affecting cell membrane properties and cell membrane permeability. For example, pH of solute. pH affects beat root pigment; when the membrane protein is damaged by high acidic pH, the dye (betaine) in the beet's roots diffuses out of the cell. The pH level is involved in regulating the function of proteins in the cell membrane. Protein is denatured with high alkalinity and acidity and decomposes lipid bilayer. For example, when using alcohol to investigate the effect of pH on the cell membrane, the use of more alcohol may cause the red pigment in the beetroot to leak further. This is because alcohol is a fatty solvent. Therefore, it dissolves cell membranes that are composed of lipids.
