What is the primary function of the nephron loop?
What is the primary function of the nephron loop?
- Prevent the diffusion of sodium into the plasma
- Passively transport water across the tubule wall
- Actively transport glucose into the plasma
- Establish a vertical osmotic gradient in the renal medulla (correct)
What is the role of the glucose transporter (GLUT) in the process of urine formation?
What is the role of the glucose transporter (GLUT) in the process of urine formation?
- Actively transports glucose across the membrane into the plasma
- Pumps sodium along with glucose out of the cell
- Facilitates passive diffusion of glucose into the plasma (correct)
- Requires energy to facilitate glucose diffusion
How is the release of glucose facilitated by SGLT during urine formation?
How is the release of glucose facilitated by SGLT during urine formation?
- By inhibiting the Na+/K+ pump activity
- By actively transporting glucose into the cell interior
- By creating an osmotic gradient in the tubules
- By releasing glucose when Na+ is released (correct)
