Which of the following is true regarding membrane asymmetry? Carbohydrates attached to membrane lipids are usually found on the cytosolic side of the membrane. A flippase causes lateral diffusion to occur very rapidly. Lateral diffusion occurs very slowly. Transverse diffusion occurs very quickly. Phosphatidylserine occurs predominantly on the inner leaflet of membrane bilayer.

Option E, Phosphatidylserine occurs predominantly on the inner leaflet of membrane bilayer.

Explanation:

Membrane asymmetry is basically the difference between two layer of the bilayer in terms of physical properties and composition.

This membrane lipid asymmetry is important for signal transduction  and cell homeostasis.  

Outer monolayer consists of phospholipids with choline  and polar  heads such as phosphatidylcholine while the inner layer has terminal primary amino group known as phospatidylserine. Cholesterol is distributed throughout the two monolayers.

Hence, option E is correct

the answer would be..

b. sucking
