QUESTION 41 Explain the roles of scramblase, flippase, and floppase in the construction of new membrane in a cell. Be sure to indicate where these enzymes are active in the cell TTTT Paragraph v Arial 3 (120) T. 12 T'T

Answer 1

Answer:- The types of phospholipid transportation enzymes are:- Scramblases, flippases, and floppases.

1) Scramblase= This protein is responsible for the translocation of phospholipids between the two lipid layer of a cell membrane. It transports the negatively charged phospholipids from the inner-leaflet to the outer-leaflet.

2) Flippases= They belong to ABC transporter family. These are transmembrane lipid transporter proteins which are located in the membrane.They play a major role in the movement of phospholipids between the two leaflets of a cell membrane.

3) Floppases=These transporters move lipids to the cytoplasmic face of the membrane are commonly called “flippases. It uses ATP to move from the outer leaflet to the inner leaflet of the plasma membrane against the concentration gradient in the opposite direction.
