What will happen if cellsnplasma membrane suddenly encounters a cold environment

At low temperature, the fatty acid tails of the phospholipids move less and become more rigid. This decreases the overall fluidity of the membrane, also decreasing its permeability and potentially restricting entry of important molecules such as oxygen and glucose into the cell.

Cells function best at normal physiological temperature, which is 98.6 degrees Fahrenheit in warm-blooded animals like humans. If body temperature increases, for example during a high fever, the cell membrane can become more fluid. This happens when the fatty acid tails of the phospholipids become less rigid and allow more movement of proteins and other molecules in and through the membrane. This can change the permeability of the cell, possibly allowing some potentially harmful molecules to enter. Both integral and peripheral proteins in the membrane can also be damaged by high temperatures and, if extremely high, heat might cause these proteins to break down, or denature.

Explanation:

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
