Which statements accurately describe how fructose metabolism in the liver differs from glucose metabolism?
The fructose 1-phosphate pathway can deplete intracellular phosphate/ATP.
Fructose enters a separate metabolic pathway from glucose, which enters the glycolytic pathway.
Two products of the fructose 1-phosphate pathway can enter glycolysis.
The presence of fructose inhibits the entrance of glucose into glycolysis.
