What is the effect of increasing temperature to the membrane of cells?

The cell membrane regulates what comes in and what leaves the cell....it kind of acts like a filter!

It is because when temperature is increased, the kinetic energy of liquid molecules increases. they collide with each other faster and the superficial(molecules on the top) molecules gain enough energy to break the bonds and set free. Thus, more and more molecules escape the surface and therefore the solubility of gases is affected i.e. it decreases.

The temperature of any material is a measure of the average kinetic energy of all the atoms in the material. As you increase this kinetic energy (temperature) then the atoms are more energetic the atoms vibrate with more energy this means each atom takes up more space and so the total volume of the material increases aswell

Within limits, as temperature increases,so does the amount of O2 released from the hemoglobin.Heat is a byproduct of the metabolic reactions of all cells and the heat released by contracting muscle fibers tends to raise body temperature.Metabolically active cells require more O2 and liberate more acids and heat.The acids and heat,in turn,promote release of O2 form the oxyhemoglobin(oxygens combined with hemoglobin).\nFever produces a similar result.In contrast, during hypothermia(lowered body temperature) cellular metabolism slows,the need for O2 is reduced, and more O2 remains bound to hemoglobin.\nSo, increased in temperature caused the cellular respiration in mammals increase too and vise versa.\nHope this help ya.

Organelles don't have much of an effect on cell function--mostly it's its shape. More active cells are smaller than less active cells so information can quickly pass through the cytoplasm and into the nucleus. This explains why muscle cells are long, small and slender, and fat cells are large and bulky. \n\nThe membrane of smaller cells has many exterior folds to increase its surface area and ablitily to collect nutrients necessary for cell function.

no, it wouldn't be easier.  Certain compounds have lower melting points than others.  Lipids for example, if you cool your body down too much become very rigid.  The resulting body temp is actually in a very important lipid range that deals with lipid and membrane fluidity.  Evolution to this is probably the result of species out competing those with lower internal temps.  Besides, our bodies naturally produce a very high amount of heat non-related to cell temperature regulation as a result of moving and living anyways.

When the temperature goes up, so does the speed of the electrons.  Faster electrons, faster bonding, faster absorbency.

yeaaaaah\n\nit's "expand and rise"\nthe energy (heat) supplied to it causes the individual molecules to have more energy and because of it, they expand further, and rise since density is lowered and volume is increased

It increases the temperature briefly.  Then entropy takes over and it assumes the ambient air temperature.

For every 10 degrees Celsius the reaction rate tends to double.  But when you raise or lower the temperature of the body so that the temperature is outside of a small range of temperatures, the enzymes and proteins do not work efficiently or at all.\n\nLower or Raise the temperature enough and you kill the organism unless it is a simple one cell thermophile bacteria.

The plasma membrane or the cell membrane is semi-permeable.Its function is to regulate the exchange of materials between the cytoplasm and extracellular fluid.

Well, the larger number of ions will increase the absorption if the volume is held constant. The increase inthe number of ions with constant volume increases the concentration of the solution and the absorbance. The relationshipe between absorbance and concentration is given by Beer-Lambert's law\nA = E*C*l where E is a constant (molecular absorptivity), C is the concentration and l is the length of light passage through the sample.\nAn increase in C will increase A.
