Who was/were the first to propose that cell membranes are phospholipid bilayers? a) h. davson and j. danielli b) i. langmuir c)
kolezko [41]

Cell membranes are first proposed to be composed of phospholipid bilayers by Singer and G. Nicolson.

<h3>What do you mean by cell membrane ?</h3>

A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The passage of chemicals into and out of the cell is regulated by the cell membrane.

  • As a result, the cell membrane has two functions: first, it acts as a barrier to keep the cell's components in and undesirable substances out, and second, it acts as a gate to allow the entry of essential nutrients and the exit of waste products.
