Question

What effect does phosphorylating a protein have on that protein? a. Phosphorylation adds energy to the protein, allowing it to form ATP from ADP and Pi. b. Phosphorylation may have no effect at all on the protein. c. Phosphorylation changes the shape of the protein, most often activating it. d. Phosphorylation adds one or more phosphorus atoms to the protein, allowing it to perform a particular function.

Answer 1

Answer:

The correct answer is (c). Phosphorilation changes the shape of the protein, most often activating it.

Explanation:

Phosphorylation referes to the enzymatic process that causes a modification of proteins following protein biosynthesis. This modifies the structural conformation of a protein, causing it to become activated, deactivated, or modifying its function.

Phosphorylation is a flexible mechanism for cells to respond to external signals and environmental conditions.

Protein phosphorylation is common among all clades of life, including animals, plants, fungi, bacteria, and archaea. The origins of protein phosphorylation mechanisms are ancestral and have diverged greatly between different species.

Abnormal protein phosphorylation has been implicated in a number of diseases like Cancer and Alzheimer's disease, Parkinson`s disease and other degenerative disorders.
