Briefly describe, how P-type transporters helps in transporting ions?
What is a secondary transporter? Why are they called secondary? What is [3 H]Leu? Explain both 3H and Leu.
When the kidneys filter plasma, the filtered glucose is reabsorbed from the renal tubules and is not passed in the urine. However, glucose can appear in the urine when the blood sugar is exceptionally high.
Given that glucose is reabsorbed by carrier-mediated transport, what functional aspect of carrier-mediated transport does the appearance of glucose in urine demonstrate? Explain.
