Protein is the important biomolecule that acts as building block of the protein. Proteins are inserted into the biological membrane and consists of transmembrane and integral membrane proteins.
The alpha helices and beta sheets are present in the bio membrane. The organism living at low temperature has high alpha helices and low beta sheets because alpha helices has high mobility, less rigidity and makes enzyme active at low temperature.
Passive diffusion is a form of passive transport and a type of diffusion by which particles from a high concentration gradient passes through a biological membrane to a low concentration gradient. Diffusion, or simple diffusion on the other hand, is the passage of molecules without the need of a membrane.
