... RNA is very similar to DNA in all ways except for a few differences. First, where the sugar in DNA is deoxyribose, the sugar in RNA is ribose. Second, where DNA is a double helix, RNA has just one strand. Third, where the bases in DNA are C,G, A and T, in RNA the bases are C, G, A and U. The U in RN ...

... because of this it skips the first priming step catalyzed by hexokinase. Since hexokinase uses on 1 ATP per glucose, only one ATP must be spent in priming glucose-6-phosphate (by PFK-1).
