Which of the following statements regarding absorption of monosaccharides is TRUE?

A. Not all monosaccharides are absorbed by active transport.

B. All monosaccharides require energy for absorption; therefore, they require active passport.

C. All monosaccharides are absorbed by passive transport.

D. Monosaccharides are simple sugars and require only direct absorption into the bloodstream.

A. Not all monosaccharides are absorbed by active transport is the correct answer.

Explanation:

Monosaccharides are simple sugar. Glucose, galactose, and fructose are examples of monosaccharides. They are the building blocks of disaccharides and polysaccharides. Monosaccharides function is to produce energy. Not all monosaccharides are absorbed by active transport because monosaccharides (galactose, glucose) are transported in the epithelial cells through protein carrier by secondary active transport and Fructose passes and absorbed entirely by facilitated diffusion.
