Answer:
b.Glucose can either be stored in the liver or sent out through the portal vein to the heart.
Explanation:
Carbohydrate which is a polysaccharide is digested into monosaccharides like glucose, fructose, and galactose. The reason why we digest polysaccharides is because polysaccharides are large biomolecules and cannot enter the blood vessels because the pores in the blood vessels are small. Our body therefore digest polysaccharides into monosaccharides which are comparatively smaller in size and can be easily absorbed by blood vessels due to their small size.
Some of the glucose which is obtained out of digestion of carbohydrates is used by our body instantly for energy production in the form of ATPs while rest of the excess glucose is transported into the liver via portal vein and stored into the liver in the form of glycogen which is also a polysaccharide but it is a branched polysaccharides. Before conversion into glycogen liver converts fructose and galactose into glucose.
Glucose molecules are used for energy in human body.
If there are excess glucose molecules then these are stored in human body in the form of fat cells.
These excess glucose molecules are also stored in liver in the form of glycogen.
All of the given statements are correct except for the statement B. Glucose can either be stored in the liver or sent out through the portal vein to the heart
