Question

When ATP molecules convert to ADP molecules, _____ occurs.

phosphorylation
dephosphorylation
elongation
specialization

Answer 1

Dephosphorylation. The product is adenosine diphosphate (ADP) and an inorganic phosphate, orthophosphate (Pi) from adenosine triphosphate (ATP).

Answer 2

The right answer is Dephosphorylation .

Dephosphorylation is the essential process of removing phosphate groups from an organic compound (like ATP) by hydrolysis. Its opposite is phosphorylation. It is found in the movement of muscles as well as in many other reactions within the organism, as well as in reactions in plants.

For example, ATP is hydrolyzed to ADP with the release of energy, phosphate groups, and ADP in the active transport of sucrose molecules within the phloem of plants.

ATP ==> ADP + Pi
