Question

Fructose is absorbed into the blood through mucosa cells of intestine by the process
called as
A) Active transport
B) Facilitated transport
C) Simple diffusion
D) Co-transport mechanism

Answer 1

Hint: Fructose is easy to digest .Fructose digestion only occurs in the liver and a high level of fructose is converted into fat in the liver which leads to obesity.

Complete answer: Fructose is a monosaccharide . After hydrolyzation of starch glucose is formed. Glucose is then converted into Fructose. The entry of fructose is through facilitated diffusion via GLUT5 and is then transported into the blood via GLU2 receptors.
-Fructose is the simplest sugar and is easy to digest. It has a ring structure i.e 6 carbon polyhydroxy
ketone structure. Fructose is abundant in fruits and is known as fruit sugar or levulose. Fructose can
only be digested in the liver in the human body.
-Fructose digestion begins in the small intestine. If sugar is present in the form of sucrose it is broken
down into glucose in the small intestine. From the small intestine, fructose molecules enter the lining bloodstream and then travel to the liver where it is metabolized with the help of aldolase B enzyme. -This process is called fructolysis. End products are then metabolized in the process of respiration.
Hence, the correct answer is Option. B
Additional information:
Commercially fructose can be derived from sugar cane, maize Excessive fructose in the body may lead to obesity, high levels of LDL and triglycerides, and insulin resistance. Fructose is also naturally found in sugar cane, beetroot, and corn.

Note: Fructose or levulose is also known as fruit sugar is commonly found in sugar cane, beetroot and is digested in the liver in the human body and is absorbed through facilitated diffusion via GLUT 5 and then is transported to the blood via GLUT 2 receptors
