As heat increases, the membranes will become more fluid and as the temperature decreases it will solidify more. i.e. butter, in the fridge its solid but if you take it out then it will eventually melt.

∙ 11y agocalcium directly decrease membrane fluidity because of the interaction with negatively charged phospholipids reducing repulsion between the polar head groups and this increades packing of the lipid molecules.This therefore causes aggregation of lipid clusters which reduses the membrane fluidity

How does the presence of cis double bonds in fatty acids affect membrane fluidity?
They tend to increase the fluidity
What are some modulators of membrane fluidity?
Some moderators of membrane fluidity are the proteins embedded in it and cholesterol molecules also.
What is the function of a cholesterol in the cell membrane?
Cholesterol is found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. It stabilizes the membrane. Only animal cells have cholesterol in their membranes.
What is the function of unsaturation in the hydrocarbon tails of membrane lipids?
increased fluidity
Does cholesterol decrease the fluidity of erythrocytes?
Cholesterol at a cellular level is used mainly in the plasma membrane of a cell. It makes up about 20% of the lipids in the membrane by weight. Because of the rigid ring structure (that makes up half of the molecule), cholesterol decreases fluidity and makes the membrane more stiff. That is the basic concept, but cholesterol usually acts as a buffer of fluidity in the membrane.It regulates the fluidity rather than effecting it in one way. At higher temperatures, cholesterol will make the plasma membrane less fluid and at lower temperatures, the cholesterol will cause the membrane to be more fluid.

What factors affect membrane fluidity?
cholesterol levels, degree of saturation of fatty acids, temperature
What are some modulators of membrane fluidity?
Some moderators of membrane fluidity are the proteins embedded in it and cholesterol molecules also.
How is fluidity reduced in animal cells?
Membrane fluidity is reduced in animal cells when there are fewer non-uniform membrane components. Membrane molecules that increase fluidity include polyunsaturated phospholipids and cholesterol molecules.
What is the function of the cholesteral in the plasma membrane?
alter membrane fluidity

Does cholesterol increase membrane fluidity?
Cholesterol increases the membranes fluidity due to the molecule having a high degree of saturation and its long length. Unsaturated fatty acid tails are kinked. As a result, the fatty acid cannot be packed as tight, which decreases the melting point. The ability of some organisms to regulate the fluidity of their membrane is called homeoviscous adaptation.
What is the function of unsaturation in the hydrocarbon tails of membrane lipids?
increased fluidity
What is the function of cholesterol in the plasma membrane?
promotes fluidity at high temperature
