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 energy and 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 increased chemical potential energy that may be used to do cellular work.

Question

Quizplus · Accepted Answer

Phosphorylation is the process of adding a phosphate group to a molecule, which typically increases its potential energy and ability to do cellular work. This occurs in ATP molecules, for example, which provide energy for many cellular processes. Therefore, a molecule that is phosphorylated has increased chemical potential energy that may be used to do cellular work.
