Refer to Figure 9

Refer to Figure 9.1 to answer the following questions.
Figure 9.1 illustrates some of the steps (reactions) of glycolysis in their proper sequence. Each step is lettered. Use these letters to answer the questions.

-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 reactivity; it is primed to do cellular work.
E) has less energy than before its phosphorylation and therefore less energy for cellular work.
