Question

2. What are the biological molecules involved in the human diet? Why are triacylglycerols not polymers? 3. Define digestion. Show three examples of extracellular digestion. Include in your description the location of the digestion, the enzyme(s) involved, and the product of the digestion. 4. How do monosaccharides, amino acids, peptides, lipids, and triacylglycerols enter the cells in the intestine?

Answer 1

Answers:-2. Biological molecules involved in human diet are carbohydrates,lipid, protein and nucleic acid.

The definition of polymer is long chain of monomers held together by chemical bond that is to say nothing but polarity and vander waal's attraction is holding the triglyceride molecules together and it is because the monomers are not joined that they can't be considered as polymers.

3. Digestion is breakdown of large insoluble food into small water soluble food molecules so that they can be absorbed by the watery blood plasma. Digestion takes place in alimentary canal by the help of enzymes like amylase, trypsin,enterokinase etc. The product of digestion is polypeptides, mono and diglycerides and glucose etc.

4. They enter into the intestine by process of both active and passive mechanism or by the help of various ions like Na+, Ca2+, Cl- etc.
