A molecule that is phosphorylated
A) has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B) has a decreased chemical reactivity; it is less likely to provide energy for cellular work.
C) has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate.
D) has an increased chemical potential energy; it is primed to do cellular work.
E) has less energy than before its phosphorylation and therefore less energy for cellular work.

Question

Quizplus · Accepted Answer

Phosphorylation is the process of adding a phosphate group to a molecule, typically through the transfer of a phosphate group from ATP. This results in an increase in the molecule's chemical potential energy, as the phosphate group is negatively charged and repels other negatively charged molecules, making it unstable and able to do cellular work. Therefore, a molecule that is phosphorylated has an increased chemical potential energy and is primed to do cellular work.
