Question

11-16 Membrane synthesis in the cell requires the regulation of growth for both halves

of the bilayer and the selective retention of certain types of lipids on one side or
the other. Which group of enzymes accomplishes both of these tasks?
(a) flippases
(b) phospholipases
(c) convertases
(d) glycosylases

Answer 1

Flippases are the group of enzymes that regulate the growth of both halves of the bilayer and retain certain types of lipids on one side or the other.

Step-by-step explanation:

The group of enzymes that accomplishes both the regulation of growth for both halves of the bilayer and the selective retention of certain types of lipids on one side or the other is (a) flippases. Flippases are a group of enzymes that are responsible for the movement of lipids across the bilayer membrane. They help maintain the asymmetry of the bilayer by transferring lipids from one layer to the other. For example, flippases can transport phospholipids from the inner leaflet to the outer leaflet of the cell membrane, allowing for selective retention of certain lipids on one side or the other.
