A) It is secreted as waste.
B) It is used only to regenerate more ATP.
C) It is added to water and excreted as a liquid.
D) It may be used to form a phosphorylated intermediate.
E) It enters the nucleus and affects gene expression.

Question

Quizplus · Accepted Answer

Inorganic phosphate may be used to form a phosphorylated intermediate, which is a molecule with a phosphate group attached to it. This process is called phosphorylation and is important in many cellular processes, including signal transduction, regulation of enzyme activity, and metabolism. Therefore, the inorganic phosphate released by ATP can be used for other important cellular reactions.
