Question : In which year did E. Gorter and F. Grendel make a breakthrough by examining the surface area of lipids and concluding that the lipid surface surrounding cells must be of two layers?
Option 1: 1910
Option 2: 1925
Option 3: 1945
Option 4: 1962
Correct Answer: 1925
Solution : The correct option is 1925.
E. Gorter and F. Grendel made their breakthrough in 1925 when they examined the surface area of lipids. They concluded that the lipid surface surrounding cells must be composed of two layers. This finding laid the groundwork for the creation of the lipid bilayer model, a key idea in cell biology, and played a significant part in the evolution of our current knowledge of cell membranes.
