Phospholipds are NOT completely hydrophilic because of The fatty acid tails The phosphate head The glycerols The glycolipids None of the above
A phospholipid can be used to do all the following except O Increase the fluidity with the presence of unsaturated fatty acid tails. create a bi-layer membrane using amphipathic properties. form a micelle using a single layer and a hydrophobic core. O connect to a glycerol molecule to create a triacylglyceride.
Fatty acids in phospholipids and triacylglycerols interact with one another by (a) disulfide bridges (b) van der Waals interactions (c) covalent bonds (d) hydrogen bonds (e) fatty acids do not interact with one another
The hydrophobic effect causes lipid molecules to aggregate. This occurs primarily in order to O decrease the ordering of water molecules around hydrophobic solutes O increase the ordering of lipid molecules in the presence of water decrease the ordering of lipid molecules in the presence of water O increase the ordering water molecules around hydrophobic solutes

The enzyme phosphofructokinase transfers a phosphate from ATP to the hydroxyl group a C1 of fructose. Similar to fructose, water also has a hydroxyl group and the concentration of water is much higher than that of fructose. Explain why the phosphate is transferred to fructose and not to water.
Select the correct statement about unsaturated fatty acids: 1. Unsaturated fatty acids have extra nitrogen atoms in their hydrophobic tails compared to saturated fatty acids 2. Unsaturated fatty acids have multiply bonded carbons in their hydrophobic tails compared to saturated fatty acids which have only single bonded carbons 3. Unsaturated fatty acids have no bends in their hydrophilic fatty acid tails 4. Unsaturated fatty acids have relatively more hydrogen atoms in their hydrophobic tails compared to saturated fatty acids
What is the structure of micelles? The polar head groups of proteins are inside the micelle and the carbon chains are outside. O Globular structure formed by small proteins in aqueous solution. The polar head groups of fatty acids are outside the micelle and the carbon chains are inside. Phospholipids are inside and cholesterol is outside of the micelle. Bile salts are inside the micelle and the carbon chains are enclosed outside.
