In General,a Signal Transmitted Via Phosphorylation of a Series of Proteins

Question

In general,a signal transmitted via phosphorylation of a series of proteins
A)brings a conformational change to each protein.
B)requires binding of a hormone to a cytosol receptor.
C)cannot occur in yeasts because they lack protein phosphatases.
D)requires phosphorylase activity.
E)allows target cells to change their shape and therefore their activity.

Accepted Answer

Phosphorylation of proteins can bring about a conformational change in the protein, thus altering its activity and transmitting a signal within the cell. This can occur in a variety of cellular processes, such as cell signaling, gene expression, and protein synthesis.
