In 1925, who extracted lipids from an erythrocyte sample and found that lipid monolayers are suitable for measuring molecular surface area versus lateral pressure?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Gorter and Grendel.
In 1925, Dutch scientists Evert Gorter and François Grendel extracted lipids from erythrocyte (red blood cell) membranes and discovered that lipid monolayers could measure molecular surface area versus lateral pressure. Their experiments suggested that cell membranes are bilayered structures, a foundational concept in membrane biology.
Why Not Others?
-
Carson & Eccles – Unrelated to lipid research (neurophysiology).
-
Avery & Buck – Known for DNA studies, not lipids.
-
Margulis & Ruska – Worked in cell biology/electron microscopy, not membrane biophysics.
