- Discuss the role of molecular chaperones in protein folding, and list some important examples of chaperonesTransmembrane portrudes on both sides. Integral protein is in the width of the bilayer and may portrude on one or both sides of the bilayer. Is Transmembrane Protein semi-similar to Integral Proteins? How can we tell the difference of the two?Non covalent bonds are very important in cell biology, could you explain why and provide an example that illustrates their importance ( do not chose protein folding as an example) What are the different levels of protein structure and what are the different parameters (sequence, type of bonds, etc...) that influence protein folding at these different levels?

Which of the following is true? a. Protein B serves as precursor for protein A b. Protein B serves as molecular chaperone for protein A c. Protein B serves as ligand for protein A d. Protein B serves as structural motif for protein AAn intermediate folding stage seen in protein denaturation or renaturation is called : a) domain b) motif c) subunit d) molten globule Proteins which do not renature spontaneously when denaturation conditions are removed may need the assistance of: a) a prosthetic group b) a higher salt concentration c) a lower temperature d) a chaperone protein The information needed for correct protein folding is encoded in: a) the surrounding molecules b) the protein’s amino acid sequence c) the pH of the aqueous medium d) the electrolyte composition of the aqueous solutionit is widely accepted that proteins can organize themselves according to a range of stable structural motifs.
