This "cell" is placed into a beaker containing water and Biuret reagent. Initially the "cell" is colorless and the beaker is light blue. At the end of the experiment, the "cell" is light purple and the beaker is still light blue. What accounts for the color change observed? O Biuret reagent entered the cell and reacted with protein. Glucose exited the cell and reacted with Biuret reagent. Biuret reagent entered the cell and reacted with glucose. O Protein exited the cell and reacted with Biuret reagent.Discuss smad pathway in details.

- A patient was admitted to the hospital with suspicion of malaria. After the examination was complete and the diagnosis confirmed, the patient was prescribed primaquine, an antimalarial drug. The drug caused a complication and led to hemolysis of erythrocytes and a decrease in the total number of circulating erythrocytes. The serening showed a glucose-6-phosphate dehydrogenase defect. Explain why the enzyme deficiency led to red blood cel hemolysis in the patient taking primaquine (the drug induces the formation of free radicals in cells). To answer: a) write a diagram ofthe process involving glucose-6-phosphate dehydrogenase; b) indicate the coenzyme of the enzyme and the reaction that includes its reduced coenzyme; c) explain the cause of RBC hemolysis in reduced coenzyme deficiency.27.
