Question

In 2003, the chemistry Nobel Prize was awarded for which of the following work?

• A. Aquaporins
• B. Na${}^{++}$ channels
• C. Ca${}^{++}$
• D. Methyl chavicol

Answer 1

The correct option is A Aquaporins

Plasma membrane is made up of phospholipids bilayer structure with embedded proteins. It is semipermeable permeable and allow for the passage of lipophilic or lipid soluble compounds and not of water soluble or hydrophilic compounds. Aquaporins are the water channels of the membrane for transport of water. The Nobel Prize in Chemistry 2003 was awarded "for discoveries concerning channels in cell membranes" jointly to Peter Agre "for the discovery of water channels" and to Roderick MacKinnon "for structural and mechanistic studies of ion channels".
