4. Starch forms a dark blue complex when treated with iodine. Partially hydrolyzed forms (still a polymer) of starch (erythrodextrin and gly- cogen) give a red complex. These colored complexes become colorless when heated but the color comes Amylosehelice with the glucose-monomerunit: OH back again upon cooling. A single drop of I, in KI solution is enough to give an unmistakable test on a solu- tion or a solid. Draw a representative alpha helix structure with I, embed- ded within each turn to represent the dark blue complex. HO OH

2. It is known hemoglobinopathies, whi ch arise due to mutations in one of histidines a- or B- chains binding with the iron in the heme gro up.These mutations stabilize the iron in Fes form. Some drugs (eg. sulfonamides) or chemicals( eg.anilin) also can cause methemoglobinemia. Suggest, how change the properties of Hb in these cas es. For this:1)Describe the structure and function of Hb A as a transport protein. 2) Explain the role ofiron ions in act ive centers of Hb for the binding of O23) How many molecules of Oz can bind mutant Hb, if mutation occurs in a- subunits? 4) Why can ascorbic acid be used to tr eat of such patients.

Cholera is a disease caused by bacteria that make cholera toxin. In the presence of this toxin, chloride ion channels in cells of the small intestine lining are stuck in their open position. As a result, an excess of chloride ions (Cl) flows from these cells into the lumen of the small intestine. Movement of Cl creates a charge gradient, so sodium ions (Na+) also flow into the lumen. Explain why the movement of these ions into the lumen results in the life-threatening diarrhea that characterizes cholera.
