What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?
fgiga [73]

The proteins exhibit four levels of organization:  

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.  

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.  

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.  

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.  

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.

Adjacent plant cells have narrow channels called plasmodesmata that pass through the cell walls of the connected cells and allow
Zepler [3.9K]
<h2>Functions of plasmodesmata</h2>

Explanation:

  • They allow the movement of cells to cells for cytoplasmic connection between different cells
  • Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.  
  • Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
  • Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
