Question

__________ molecules disrupt the close packing of fatty acyl chains and interfere with their mobility

Answer 1

Unsaturated fatty acids disrupt the close packing of fatty acyl chains and interfere with their mobility by introducing kinks in their tails, preventing tight packing and resulting in a more fluid bilayer.

Step-by-step explanation:

In the context of the question, the molecules that disrupt the close packing of fatty acyl chains and interfere with their mobility are unsaturated fatty acids. Unsaturated fatty acids have kinks in their tails that prevent tight packing, resulting in a more fluid bilayer. This is in contrast to saturated fatty acids, which pack tightly together and create a rigid bilayer.
