How does it affect the fluidity of the plasma membrane? 17 Polypeptide sequences are polymers of many amino acids linked by peptide bonds. Would you consider this term to be s ynonymous with protein? Why or why not? How would you explain the formation of a multi-subunit protein?Explanation / Answer
15. Cells located on the paws of a polar bear is mostly composed of unsaturated phospholipids to acclimatize to the chilling cold environment which imparts fluidity in the cell membrane and maintains the cell integrity to properly function without getting damaged.
16. Cholesterol is a crucial component of the cell membrane, it acts as a regulator of membrane fluidity. Cholesterol increases the membrane fluidity at low temperature and decreases the fluidity at a higher temperature to prevent damage at extreme temperature range. The cholesterol molecule is placed between the adjacent phospholipid in the membrane thereby regulating the fluidity of plasma membrane.
17. We know that amino acids are the building blocks of protein. This term is synonymous with protein because whether a complex or simple protein it is composed of polypeptide chains interlinked by hydrogen bonds and disulfide linkages to be fully functional in nature.
Multisubunit protein can be of two types homomultimeric and heteromultimeric. It is an association of two fully folded proteins binding among them at a specific region to carry out a specific task of a cell.
