c) Based on the proposed signaling pathway, predict the relative amount of phosphorylated to unphosphorylated kinase D in the Brec-WT cells when the cells are grown in nutrient broth lacking B . Justify your prediction.

Answer:

As has been said, the whole protein A contributes to something like the increase in the level of motivation as well as the blood supply vessels throughout the cell.

Explanation:

  • It, therefore, takes place because once signal B has been available throughout the broth including its nutrients, the whole B connects to something like the untamed protein Brec, which also initiates signaling pathways. Throughout the existence of modulation, there's D phosphorylation, which would be transformed to D phosphorylate.
  • However, if the B sensor isn't present throughout the nutrient broth, there'll be no stimulation including its Brec receptor, hardly any phosphorylation including its D nutrients. Throughout this circumstance, this same total number of phosphorylating D would be much less throughout the cell than those of nonphosphorylated D.

Here anyway, the total proportion of phosphorylated protein kinase D is still less than D protein.

The relative amount of phosphorylated kinase D will be less than the unphosphorylated Kinase D protein as lacks the first messenger B.

It is given that protein A is involved in the stimulation of growth and blood vessels form in the cell.

In presence of first messenger B:

  • The process takes place when signal B is present in the nutrient broth, this B attaches to Brec wild protein which initiates the signaling cascade.
  • In presence of signaling, there is phosphorylation of D ( inactive), which is converted into phosphorylated D ( activated ).

In absence of the first messenger B:

  • So if signal B is absent in the nutrient broth, then there will be no activation of the Brec receptor and no phosphorylation of D protein.
  • In this condition, phosphorylated D amount will be less in the cell than unphosphorylated D.

Thus, the amount of phosphorylated kinase D will be less than the unphosphorylated Kinase D protein.
