A 41-year-old male presents to the emergency room complaining of frequent urination, increased hunger, "always being thirsty," and fatigue. He is diagnosed with type 2 diabetes mellitus
a. In explaining to him the physiological reason for his symptoms, what cellular functions do you think would help him understand his disease?
b. How might you explain his fatigue on a cellular level?
- Facilitated diffusion occurs through a transport protein that is not linked to metabolic energy. Glucose cannot pass unassisted through the cell membrane because they are not lipid soluble or are too large to pass through the membrane's pores.
- Glycolysis is the process by which energy is liberated from glucose, and fatigue in type 2 diabetes mellitus is caused by the inability to utilize this within the cell.
