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.
A selectively permeable membrane allows materials (some substances or molecules) needed for survival in and out. (Like a filter)
The Nonsense mutation, also called stop mutation, is a gene mutation that results in a change in the amino acid sequence that leads to a premature stop (G).
