The low incidence of protein or lipid flip-flop in a membrane preserves:
A) membrane fluidity.
B) membrane melting temperatures.
C) membrane asymmetry.
D) All of the above.
E) None of the above.

Question

Quizplus · Accepted Answer

Protein or lipid flip-flop in a membrane would disrupt the asymmetry of the membrane, and therefore the low incidence of protein or lipid flip-flop preserves membrane asymmetry. The preservation of membrane asymmetry is important for proper cellular function and signaling. The low incidence of protein or lipid flip-flop does not directly impact membrane fluidity or melting temperatures.
