Question

question 5 (1 point) research showed that river temperature and pollution are increasing. why is membrane fluidity critical for cell survival? a) it allows components to move and interact within the membrane b) it prevents the exchange of molecules across the membrane c) it ensures that the membrane remains static and unchanging d) it allows lipids to flip between layers

Explanation:

Cell - membrane fluidity is crucial as it enables components like proteins and lipids to move and interact, which is necessary for functions such as signal - transduction and membrane repair. Option b is incorrect as membrane fluidity promotes molecule exchange. Option c is wrong since fluidity implies movement, not static nature. Option d is a part of membrane dynamics but not the most comprehensive reason for its importance for cell survival.

Answer:

a) It allows components to move and interact within the membrane
