Membrane Transport and Extreme cold tolerance Essay

Membrane Transport and Extreme cold tolerance - Essay Example There are different types of membranes like the plasma membrane. The plasma membrane serves the purpose of ensuring effective transportation of compounds like nutrients, ions and metabolism. The plasma membrane provides a wall or separation between extracellular and intracellular spaces and serves a critical and important function in exchange of materials. The membrane also serves as a detective by transmitting extracellular stimuli signals. The transmission of the signal is done by the proteins contained in the membrane. The membrane is made in a way in which it withstands stress stimuli from the extracellular space. For effectiveness of transportation of compounds, the membrane should adopt to all types of stress including hot, cold and warm climates. In case the membrane is not able to cope with the stimuli in the extracellular space, transportation of materials does not take place. The cells which adapt to the stress have proteomic properties which help the cell to adopt to any e xternal condition. For growth and living a health life the organism should have a membrane that can adopt any condition.Any membrane like the plasma membrane is made to adapt to abiotic stresses. The abiotic stresses restrict the growth, distribution and reproduction of an organism. The abiotic stresses include things like extreme cold temperature, light, drought, salt and physical pressure among others. The availability of the proteomics in a membrane has shown that organism is able to cope with extreme cold temperature.
