Glucose and galactose enter intestinal cells by co-transport with sodium. How does fructose enter?

1. All carbohydrates are absorbed as monosaccharides, at a rate of about 120 grams per hour. 2. Glucose and galactose share common protein carriers and move by co-transport with sodium ions. 3. Fructose does not use that sodium-linked route. 4. It is absorbed and transported by facilitated diffusion alone, using a carrier but no energy input. 5. That is why the option naming co-transport with sodium is the trap set by the stem itself. 6. Active transport and endocytosis both consume ATP, which facilitated diffusion does not. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.7 Chemical Digestion and Absorption: A Closer Look_
