Select оne pаthоlоgicаl condition (e.g., cystic fibrosis, musculаr dystrophy, metastatic cancer) and discuss how a dysfunction at the cellular-structure level (plasma membrane, cytoskeleton, junctions, endomembrane system) influences that disease (250 words). You can choose any of the following — pick one you feel comfortable with:Example DiseaseKey Structure InvolvedWhy It’s Good for This QuestionCystic Fibrosis (CF)Plasma membrane transport protein (CFTR chloride channel)Classic link between membrane protein malfunction and systemic effects.Duchenne Muscular Dystrophy (DMD)Cytoskeleton–membrane linkage (dystrophin complex)Clear link between defective cytoskeletal support and muscle cell damage.Metastatic CancerCytoskeleton & Cell JunctionsShows how structural remodeling enables invasion and metastasis.In order to answer this question please follow these guidelines:Briefly introduce the disease (what it is, what systems it affects).State which cellular structure is primarily involved.Include a thesis statement: show that you will explain how this structural dysfunction causes the disease phenotype.Describe what the relevant structure does in healthy cells.Explain the specific defect (mutation, misfolding, degradation, autoimmune damage, etc.).Describe how that defect alters the cell’s structure and function (e.g., misfolded protein retained in ER, defective channel, loss of cytoskeletal support).Link the cell-level defect to tissue-level dysfunction.Example: defective chloride transport → dehydrated mucus → blocked airways (CF).Example: absent dystrophin → muscle membrane tears → cell death → muscle weakness (DMD).Summarize how the structural dysfunction explains the pathology.
