Question
Select all of the following that are functions of membrane proteins. Please specify the only one that would apply.
*transport chemicals into and out of cell
*form plant cell wall
*provide binding site for cholesterol
*serve as recognition molecules
*anchor cell membrane to cytoskeleton
II.Suppose a researcher successfully produced a membrane composed of saturated triglycerides rather than from phospholipids. What characteristics would you expect the saturated triglyceride membrane to have? Select all that apply. (Hint: Review saturated fats in section 2.5E.)Please specify the only one that would apply.
*Hydrophilic molecules would easily pass through the membrane.
*hydrophobic molecules would be attracted to the membrane.
*the membrane would be fluid at room temperature
*the saturated triglycerides would not form a bilayer.
Explanation / Answer
1. All that apply - transport chemicals into and out of cell, provide binding site for cholesterol, serve as recognition molecules, anchor cell membrane to cytoskeleton
only one that would apply. - transport chemicals into and out of cell
2. all that apply - hydrophobic molecules would be attracted to the membrane, the membrane would be fluid at room temperature, the saturated triglycerides would not form a bilayer.
only one that would apply. - the saturated triglycerides would not form a bilayer.
Triglycerides are heavily nonpolar and tend to form aggregates in polar solvents such as water. No it not able to form bilayer like phospholipidbilayer.
