The role of BiP in protein folding was briey described in this chapter. Answer the following questions
NISA [10]
<h2>KDEL Sequence & Protein Unfolding</h2>

Explanation:

(a) The distinction between proteins sent out from and those held in the ER has all the earmarks of being represented by two unmistakable sorts of focusing on successions that explicitly mark proteins as either bound for transport to the Golgi or bound for maintenance in the ER. Numerous proteins are held in the ER lumen because of the nearness of the focusing on grouping Lys-Asp-Glu-Leu (KDEL, in the single-letter code) at their carboxy end. In the event that this succession is erased from a protein that is regularly held in the ER (e.g., BiP), the transformed protein is rather moved to the Golgi and emitted from the cell. On the other hand, the expansion of the KDEL arrangement to the carboxy end of proteins that are typically discharged makes them be held in the ER. The maintenance of some trans membrane proteins in the ER is comparatively directed by short C-terminal successions that contain two lysine deposits (KKXX sequences)

(b) Proteins are large molecules composed of folded chains of amino acids. Every protein has a unique shape and that shape determines the things it does. You could think of them as keys that fit into certain locks around the body Proteins do lots of different things around the body, including speeding up biological processes, recognizing antibodies, providing structure to certain body parts, transporting substances, regulating genes, and responding to signals inside and outside the body Proteins range in size from small ones, such as insulin - only 51 amino acids long, to extremely large ones, such as titin almost 27,000 amino acids long. No matter their size, they must be folded into a particular shape in order to function. Sometimes, though, things go wrong and cause the protein to unfold

3 main stages of translation
taurus [48]

Translation proceeds in three phases: Initiation: The ribosome assembles around the target mRNA. The first tRNA is attached at the start codon. Elongation: The tRNA transfers an amino acid to the tRNA corresponding to the next codon.

Which of these changes to a modern lifestyle would promote the development of more-sustainable practices in the world food syste
dezoksy [38]

Answer:

c. switching from beef to soy

Explanation:

Switching from beef to soy shall lead to the curbing of lifestyle diseases such as obesity.

At the same time, soy shall provide the nutrients that were needed by the body and could be obtained from beef.

Beef is much expensive compared to beef, thereby, there shall be experienced  low expenditure compared to beef.

Therefore the switching from soy to beef shall be a more sustainable food system.

When cells communicate by the signaling process, one cell produces a _________________blank that must be received by the _______
My name is Ann [436]

When cells communicate by the signaling process, one cell produces a signaling molecule that must be received by the signal receptor on or in the responding cell. Signaling molecules are often called ligands, a general term for molecules that bind specifically to other molecules (such as receptors).
