In the Regulation of Chemotaxis, Proteins are Modified in Which

Question

In the regulation of chemotaxis, proteins are modified in which of the following ways?
A) phosphorylations
B) methylation
C) feedback inhibition
D) phosphorylation and methylation
E) feedback inhibition, phosphorylation, and methylation

Accepted Answer

Proteins involved in chemotaxis are primarily modified through phosphorylation and methylation. These modifications can alter the activity or localization of the proteins, leading to changes in cell movement in response to chemical signals. Feedback inhibition is not a form of protein modification, but rather a regulatory mechanism in which the end product of a pathway inhibits an earlier step in the pathway.
