In the described fructose pathway, fructokinase forms fructose-1-phosphate, and aldolase B deficiency can cause hereditary fructose intolerance.
Answer
true
Explanation
### Why this is right
The liver fructose pathway begins with fructokinase producing fructose-1-phosphate. Aldolase B then cleaves that intermediate, and its absence is associated with hereditary fructose intolerance.
### The concept
This route differs from hexokinase conversion of fructose to fructose-6-phosphate. The enzyme deficiency is tied to a specific metabolic route and should not be confused with galactose-processing disorders.
### Terms
- **Fructokinase**: The enzyme that phosphorylates fructose to fructose-1-phosphate.
- **Hereditary fructose intolerance**: An inherited disorder associated with aldolase B deficiency.
### Remember
Fructokinase makes fructose-1-phosphate; aldolase B processes it.
