In the assembly of a lipid layer in a polar solvent like water, the stacking of hydrophobic tails eliminates the need of surrounding water molecules to be ordered around the individual tails, which results in a(n) _________ in entropy. As a result, the ∆G of the system ________.
Select one:
a. decrease; decreases
b. decrease; increases
c. increase; increases
d. increase; decreases
Homework Answers
Ans B option , entropy decreases and ∆G increases
As the hydrophobic tail of fat or oil eliminates water that cause removal of unfavourable interection between polar and nonpolar molecule and hence stability increases and hence degree of randomness decreases which is represented by entropy so finally entropy decreases.
For ∆G which is Gibbs free energy and for stable reaction or unfavourable reaction ∆G will be positive so since overall system move here toward stablity so ∆G will be positive.
Hope it's clear.thanks

Protein folding and lipid-bilayer formation result in decreased entropy for a protein molecule and bilayer components. The decrease entropy of the surrounding entropy is balanced by a large increase in the OTemperature Salt solutions Pressure Water molecules Water's ability to dissolve a wide variety of molecules is important, but more important is the hydrophobic effect, which drives the aggregation of nonpolar molecules and plays a role in the folding of proteins and formation of lipid bilayers.

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...

QUESTION 8 When phospholipids are mixed with water, they spontaneously form lipid bilayers. Why is this energetically favorable A. None of these answers are correct B. Hydrogen bonds form between neighboring polar head groups of phospholipids, drawing them together. C. Van der Waals interactions between the hydrocarbon chains are stronger than hydrogen bonding interactions. D. Water molecules would otherwise form cage-like structures around the hydrocarbon chains, decreasing entropy. E. All of these answers are correct
