When ATP releases some energy, it also releases inorganic phosphate. What happens to the inorganic phosphate in the cell?

A) It is secreted as waste.

B) It is used only to regenerate more ATP.

C) It may be used to form a phosphorylated intermediate.

D) It enters the nucleus and affects gene expression.

The correct answer is: C) It may be used to form a phosphorylated intermediate.

Released phosphate-inorganic phosphates form a 'pool' of phosphates within the cells. From there, they can be used for different reactions, into a variety of biosynthetic pathyways. Some of those reactions are formation of GTP, ATP, the ribonucleotides, protein phosphorylation etc.
