Current Question (ID: 12654)

Question:

According to fluid mosaic model of plasma membrane the quasifluid nature of

Options:

1. Protein enables lateral movement of lipids within in the overall bilayer
2. Lipid and protein enable the lateral movement of carbohydrates
3. Lipid enables lateral movement of proteins within the overall bilayer
4. Lipid enables the flip-flop movement of proteins

Solution:

The lipid bilayer provides a fluid matrix for the lateral movement of proteins within the membrane. This is due to the amphipathic nature of the phospholipids, which forms a bilayer, and the hydrophobic and hydrophilic regions of proteins that can interact with the lipid bilayer. The model suggests that the plasma membrane is a dynamic structure in which the components, including lipids and proteins, are free to move and interact with each other.
