He has also been experiencing intermittent diarrhea and skin abscesses since birth. Otherwise, he has been meeting developmental milestones as expected. Analysis of this patients sputum reveals acute angle branching fungi, and culture shows gram-positive cocci in clusters. A flow cytometry reduction test was obtained that confirmed the diagnosis. Which of the following processes is most likely defective in this patient?? A: Actin polymerization, B: Leukocyte migration, C: Maturation of B-cells, D: Transforming oxygen into superoxide radicals, E: Transforming superoxide radicals into hydrogen peroxide,  <response>: This is a medical case about an 8-month-old boy with fever, cough, diarrhea, and skin abscesses since birth. The clues given are:- Acute angle branching fungi in sputum indicates fungal pneumonia, likely caused by Aspergillus.- Gram positive cocci in clusters indicates Staphylococcus aureus infection. - Flow cytometry reduction test confirmed diagnosis, which indicates an immunodeficiency disorder.The question asks which process is most likely defective in this patient. Based on the recurrent infections and immunodeficiency, this patient likely has chronic granulomatous disease CGD. CGD is caused by defective NADPH oxidase, which converts oxygen to superoxide radicals used to kill pathogens.D: Transforming oxygen into superoxide radicals
