Question

Compare and contrast flippases, floppases and scramblases with respect to their functions and specific actions.

Answer 1

Flippase- These are transmembrane fat transporter proteins which causes movements of phospholipids across the cell membrane(transverse diffusion).

They generally transports the lipid from exoplasm to the cytoplasm.

Floppase- These transport the lipids from inside the cells to the outside.

The process requires ATP and occurs against the concentration gradient.

Scramblases- these are the transport channels present in the cell membrane that can cause the movement of lipid in any direction according to the equilibrium.
