Question

Who proposed the unit membrane model of plasma membrane?

• A. Robertson
• B. Singer
• C. Danielli
• D. Robert Hook

Answer 1

The correct option is A Robertson

Robertson proposed unit membrane concept for biological membranes. According to this concept, the biological membrane is a lipid bilayer surrounded on either side by proteins with a difference in their type for the outer and inner side. All biomembranes have a trilaminar structure with an electron transparent lipid bilayer (35 $\mathring{A}$) lying sandwiched between electron dense protein layers (20 $\mathring{A}$ each).
