Question

Anonymous 1 year as Applying the Scientific Method to investigate Cell Structure Imagine that you are part of a research team that specializes in diagnosing disorders associated with malfunctioning cellular structures, Medical doctors consult your group to help diagnose particularly difficult cases. You have been presented with the following data Patient History: Seven year old boy o Fatigue o Muscle weakness o low endurance o Loss of coordination o Progressive difficulty walkin Physical Examination Muscle loss & deformity Awkward at o Difficulty breathing Laboratory Results o Cells have abnormal shape o Cell division is abnormal o impaired intracellular movement of material Explain which structures may be involved. Use the patient history data to support your conclusions.

Answer 1

The diagnosis of this case is Malfunctioning Organalle: Cytoskeleton

Cytoskeleton role is to support the cell, pull apart chromosomes in mitosis, moves materials inside the cell,

Actin and myosin; two microfilaments, cause muscle contractions(Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events.)
So, a malfunction causes abnormal cell shape, cell division, faulty movement of cellular materials and muscle loss and deformity.

Based on the lab reports we can see that,

• The cytoskeleton helps in cell division and that was one of the problems with the cells.
• The intracellular movement of materials in the cell is also controlled by the cytoskeleton, which is impaired
• The Cytoskeleton retains the cell structure, and the cells in the patient's body are irregular
• The loss of muscle is also due to the cellular abnormality in shape and the malfunction of the actin filaments in the cytoskeleton.
• And so now the muscles which are deformed in the lungs and the muscles in the legs which cause the difficulty in breathing and the awkward gait.
