Why cooling denatured protein is not likely to reverse the effects of denaturization
Denaturation
Denaturation of Protein which it's original shape gets destructed because of the breakage of chemical bonds which is already weak, and the separation of the interactions. Due to this effect Proteins become biologically inactive. It's inability to function is due to the disappearance of three dimensional structure, secondary, tertiary and quaternary structures. This leads to the changes even in the physical, chemical and biological properties of proteins. In simple, the conversion of well defined folded structure to unfolded state is called Protein Denaturation
Mainly reverse denaturation can be easily achievable, the reason is because of the facts that the amino acids which is held by the covalent bonds are in the exact sequel and the polypeptide primary structure. But this irreversibility is not possible in Cold denaturation of proteins.
Cold denaturation of proteins
The process in which the molecules are very stable at minimum temperatures and thermal fluctuations.
Cold denaturation causes limited unfolding of polypeptide chain. This leads to the alteration in the association of the water and hydrophobic groups. Falling off temperature results in the boosting of hydration. This is due to the decrease in the poor association of non polar residues with water. In other words, free energy cost for hydrophobic effect. Lower Temperature will result in diminishing hydrophobic effect and the depletion of tertiary structure.
Hydrogen bonds present in the interfacial water are more affirmative than the hydrogen bonds in the bulk water for cold denatured systems. Approximately this leads to the consideration of the unfolding process.
In Simple, Reduction in the flexibility will restrict the molecules from chemical reactions and binding nature with other molecules. When the temperature decreases the enzyme activity decreases, so it is not likely to reverse the effects of denaturisation.

4. Explain why a denatured enzyme in a cell could be detrimental. 5. If you did not stop the reaction, would products continue to be produced indefinitely? Explain. 6. Cells often use the product as an inhibitor to slow or stop enzymatic activity. What is an advantage to doing so?
In the lac operon, what are the likely effects on operon transcription of the mutations listed below? PLEASE EXPLAIN your answers. I think I answered the first part of the question but need help explaining why. Mutation of the consensus sequence in the lac promoter. i. Transcription is blocked. Mutation of the repressor binding sites in the operator sequences. i. Transcription is constitutive. Mutation of the lacI gene affecting the allosteric site of the protein. i. Transcription is blocked. Mutation...
5. The hypothetical protein E contains no tyrosine residues and 3 tryptophan residues. When in the native folding state, protein E displays maximum emissions at 302 and 330 nm when excited using light at 280 nm. However, when denatured, the observed emission maximum shifts to 350 nm. Please explain briefly why two separate emissions maxima are observed in the native state (address intra- or inter-molecular interactions). Also, please briefly explain why such a shift in emissions occurs upon protein unfolding...
1. Can physical symptoms be caused by thoughts? Explain why it is or isn’t possible. Be sure to provide justification from the readings for your reasoning. 2.Would it be better to cope with stress by changing thoughts, behaviors, or physiological responses? Would it be better to cope with stress by changing a combination of all three? Why would it be better to change just one or all three? Provide justification.
