Question

Discuss the general structure of transmembrane segments, noting the types of amino acids that are typically found in these segments Explain how organisms that cannot regulate their temperature maintain the appropriate membrane fluidity at different temperatures (homeoviscous adaptation) and describe an example of a way in which these organisms can indirectly sense temperature changes and react to such changes (hint: oxygen solubility) Discuss the general structure of transmembrane segments, noting the types of amino acids that are typically found in these segments Explain how organisms that cannot regulate their temperature maintain the appropriate membrane fluidity at different temperatures (homeoviscous adaptation) and describe an example of a way in which these organisms can indirectly sense temperature changes and react to such changes (hint: oxygen solubility) Discuss the general structure of transmembrane segments, noting the types of amino acids that are typically found in these segments Explain how organisms that cannot regulate their temperature maintain the appropriate membrane fluidity at different temperatures (homeoviscous adaptation) and describe an example of a way in which these organisms can indirectly sense temperature changes and react to such changes (hint: oxygen solubility)

Explanation / Answer

Answer
Transmembrane protein are basically alpha-helix in nature. It passes the membrane bilayer.The hydrophilic region of the protein remain outside toward the water and hydrophobic region embedded into the membrane to pass.There are presence of non polar amino acid in this region.

Homeoviscous adaptation: It is the adaptation of a lipids present in the plasma membrane for maintaining the fluidity of a membrane.
Example: Animal exposes to cold temperature then it will increase the unsaturated lipid content in the membrane which increase the fluidity of the membrane and if the temperature increases then the fluidity of the membranes is decreases.
