MCQ

Question

Most organisms can regulate membrane fluidity by changing the lipid composition. If cells are transferred from a warm environment to a cold one, it can be expected that:

Options

Choose one · Correct answer highlighted

There will be a decrease in the proportion of 16-carbon fatty acids compared to 18-carbon fatty acids There will be an increase in the proportion of 16-carbon fatty acids compared to 18-carbon fatty acids Correct There will be an increase in the proportion of saturated fatty acids Phospholipids will not be incorporated into the membrane

Explanation

In cell biology, cellular compartmentalization and cell cycle dictates that SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Therefore There will be an increase in the proportion of 16-carbon fatty acids compared... is correct as it aligns with membrane trafficking and cell cycle control, supported by mechanistic studies
