Question

which of the following are not enzymes involved in moving phospholipids from one leaflet to another

12. Membrane dynamics Page: 396 Difficulty: 2-。Ans: C Which of the following are not enzymes involved in moving phospholipids from one leaflet to another A) Flippases that move phosphatidylethanolamine and phosphatidylserine B) Floppases that move phospholipids from the cytosolic leaflet to the extracellular leatiet C) Flip-floppases that allow phospholipids to move back and forth between the inner and outer leaflets D) Scramblases that allow phospholipids to move down their concentration gradient E) Phosphatidylinositol transfer proteins that play a role in lipid signaling

Answer 1

C) Flip-floppases that allow phospholipids to move back and forth between the inner and outer leaflets.

Flip-floppases are not enzymes involved in moving phospholipids from one leaflet to another.
