Select the Phosphorylation Reaction

Question

Select the phosphorylation reaction.
A) Glucose + fructose → sucrose + H2O
B) Glucose + ATP → glucose-P + ADP
C) Glucose-P + fructose → sucrose + Pi
D) Glucose + glucose → maltose
E) Sucrose + H2O → glucose + fructose

Accepted Answer

Phosphorylation reactions involve the addition of a phosphate group to a molecule. In choice B, glucose is phosphorylated to glucose-P (glucose phosphate) using ATP, which is a classic example of a phosphorylation reaction.
