The presence of phospholipids with increase number of double bonds will increase membrane fluidity.
Cell membrane are composed of carbohydrates, proteins and mainly phospholipids. Membrane fluidity depends on two things : phospholipids and cholesterol present in membrane.
Membrane Phospholipids mainly are two types: saturated and unsaturated. Saturated fatty acids are single bond and straight but unsaturated fatty acids are double bonded and as result of increasing double bond makes more fluidity of membrane.
If any question, please comment.

A cell membrane consists of a lipid bilayer, which is a double layer of phospholipids. Each phospholipid has a hydrophilic phosphate head and a hydrophobic lipid tail. These phospholipids are not chemically bound to one another, but rather maintain their structure due to the fact that the lipid tails do not like water. They're hydrophobic^2. If they all buddy up, then they can all stay dry. (See figure.) One way to deal with this quantitatively is to realize that there...

When grown at higher temperatures, bacteria and yeast maintain an optimal membrane fluidity by doing which of the following? Choose one: o producing membrane lipids with tails that are shorter and contain fewer double bonds o producing membrane lipids with tails that are longer and contain more double bonds o adding cholesterol to their membranes o producing membrane lipids with tails that are shorter and contain more double bonds o producing membrane lipids with tails that are longer and contain...

- By varying the number of double bonds in the hydrophobic tails of phospholipids, animals can maintain the integrity of their cell membranes in the face of changes in TB. How do they achieve this? - The veterinary hospital at the University of Franca in Sao Paulo, Brazil had five giant anteaters (Myrmecophaga tridactyla) needing surgical treatment under anesthesia for a variety of disorders. Unfortunately, there are no doses indicated on any anesthesia for application to anteaters. How did these...

1. What type of bonding is present in phospholipids-ionic or covalent? Explain! You will notice there are several double bonds contained in a phospholipid. What is a double bond and how does it influence the shape of a molecule"? 2. Phospholipids are said to be amphipathic-that is they have one region that is polar and another that is nonpolar. The end containing the phosphorous and nitrogen is the polar end. Can...
