Correct option is B
- The fluid mosaic model was proposed by Singer and Nicolson in 1972 and quickly became the foundational framework for understanding the structure and dynamics of cellular membranes.
- This model describes the membrane as a fluid bilayer of lipids with proteins embedded in or associated with the bilayer, allowing for lateral movement.
Additional Information:
- The fluid mosaic model revolutionized the understanding of biological membranes, explaining how the membrane's fluid nature allows dynamic processes such as protein movement, membrane fusion, and selective permeability.
- It provided insights into the amphipathic nature of lipids, where hydrophilic heads face outward and hydrophobic tails face inward, forming a bilayer.
- The model also accounts for the diverse functions of integral and peripheral proteins, such as signal transduction, transport, and cell recognition.
