Question

In ______, Gorter and Grendel extract lipids from blood cells. After evaluating them, they propose membranes are made of a ____________.

Answer 1

The correct answer would be - 1925, phospholipid bilayer.

Step-by-step explanation:

Gorter and Grendel performed an experiment in 1925 to extract lipids from blood cell and after extracting the protein they evaluated red blood cell membrane.

They found out that plasma membrane have two lipid layer and these lipids are made of phospholipids. Phospholipids are phosphate group that are attached with the lipid molecule.

Thus, the correct answer would be - 1925, phospholipid bilayer.
