Phosphatidylethanolamine is concentrated in the inner leaflet of the plasma membrane and tends to promote the curvature of the membrane, which is important in _________.
A)membrane budding
B)membrane fragmentation
C)membrane fusion
D)signal transduction and membrane fusion
E)both membrane budding and membrane fusion

Question

Quizplus · Accepted Answer

Phosphatidylethanolamine plays a crucial role in membrane dynamics, including promoting membrane curvature. This curvature is essential for processes like membrane budding and fusion, where the membrane undergoes significant shape changes to facilitate various cellular activities such as vesicle formation and the merging of membranes during vesicle trafficking or cell fusion.
