1) Describe the role of the signal sequence and the signal recognition particle (SRP) in targeting and processing proteins in the endoplasmic reticulum. 2) What is the function of the trans-Golgi network?

Integral membrane proteins are anchored in lipid bilayers. Which of the following groups of amino acid residues would likely be found in the portion that crosses the lipid bilayer? Nonpolar Polar Acidic Charged

What could happen to the proteins of cells treated with high amounts of free radicals that would effect the diffusion of those treated cells?

How common are type I, type II, and type III membrane proteins?

What features in the chemical composition of phospholipids make them ideal components of the cytoplasmic membrane?

Cell membranes are fluid, and thus proteins can diffuse laterally within the lipid bilayer. However, sometimes the cell needs to localize proteins to a particular membrane domain. Name three mechanisms that a cell can use to restrict a protein to a particular place in the cell membrane.

What is an advantage of receptor mediated endocytosis as compared to pinocytosis? Then what is an advantage of pinocytosis compared to receptor mediated endocytosis?

where is Peripheral membrane protein made and how does it transfer to the membrane?

Consider two different proteins that are leaving from the Golgi in order to arrive in their common destination, a lysosome. In order for these two different proteins to be sent to the same place, what should they have in common? A) They must have the same primary structure B) They must have been imported into the cell by endocytosis. C) They must have the same tertiary structure D) They probably have the same glycosylation pattern. ..
