Question

Multiple Select Question Select all that apply How does lipid composition affect membrane fluidity? Saturated fatty acids tend to make the membrane less fluid because they pack together well. Sphingolipids tend to make the membrane less fluid. Unsaturated fatty acids tend to make the membrane less fluid because kinks introduced by the double bonds keep them from packing together well. Lipid composition has no effect on the fluidity of membranes.

Answer

- Saturated fatty acids tend to make the membrane less fluid because they pack together well.- Sphingolipids tend to make the membrane less fluid.

Explanation

Membrane fluidity is influenced by the types of lipids present. Saturated fatty acids pack tightly, reducing fluidity. Sphingolipids also reduce fluidity due to their structure. Unsaturated fatty acids increase fluidity because the kinks from double bonds prevent tight packing. Lipid composition significantly affects membrane fluidity.
