BIO SCI E109 Chapter Notes - Chapter 5: Uric Acid, Insulin, Transcytosis
Document Summary
[diffusion+protein-mediated transport+vescular transport+epithelial transport: carrier-mediated transport [protein-mediated transport] Specificity: glut transport monosaccharide only, not disaccharide. (12 glut genes) Competition: competitive inhibitor gout : a disease caused by elevated levels of uric acid in the plasma cure by enhancing the excretion of in the urine. uric acid. Kidney"s oat (organic anion transporter) reclaims urate (the anion form of uric acid) from the urine and returns the acid to the plasma. But if an organic acid called probenecid is administered to the patient, oat binds to probenecid, thus preventing the absorption of urate. Saturation: transport maximum (the maximum transport rate: vesicular transport. Phagocytosis: actin-mediated process(use the cytoskeleton) form phagosome fuse with lysosome. [occurs in certain types of white blood cells called phagocytes (eat bacteria, and some foreign particles(usually larger, not pro. ))] Endocytosis: [two differences from phagocytosis: membrane surface indents rather than pushes out + forms smaller vesicles and is constitutive(always take place)].
