In organisms living in extremely cold environments, the plasma membrane remains fluid. This adaptation is achieved by increasing the proportion of which membrane component?
Q1. In organisms living in extremely cold environments, the plasma membrane remains fluid. This adaptation is achieved by increasing the proportion of which membrane component?
Answer: Unsaturated fatty acids
Explanation: Unsaturated fatty acids prevent tight packing, maintaining fluidity at low temperatures. Cholesterol is tempting but it acts as a fluidity buffer, not the primary cold-adaptation.
