From what you should now know about bacterial taxis and nodule formation, predict how a rhizobium would respond to a flavonoid.
andreev551 [17]

Answer;

-The bacterium would exhibit positive chemotaxis.

Explanation;

-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.

Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.

Predict where the structural differences would occur between an-pep and other enzymes that do not digest the peptides.
kramer

AN-PEP enzyme refers to a dietary supplement, which has been shown to dissociate gluten in the stomach. It has been proven to help the individuals suffering from Gluten sensitivity or Celiac disease. The scientific name of the enzyme is Aspergillus Niger prolyl endoprotease.  

However, certain structural differences would take place between AN-PEP, which prevent the enzyme from digesting the peptides. Some of the differences like amino acid differences would be expected in the active site, and in the regions, which influence the folded composition of the active site.
