Imagine that a eukaryotic cell carries a mutation impairing its ability to phosphorylate glucose during glycolysis. What is a likely result of this mutation?
A) High (possibly toxic) levels of glucose would accumulate in the cell.
B) Glucose could move out of the cell, slowing cellular respiration.
C) Because phosphorylation stabilizes glucose, glucose would spontaneously form pyruvate.
D) Without the phosphorylation of glucose, glycolysis would consist entirely of exergonic reactions.
E) More pyruvate would be formed at the end of glycolysis.
