    Incorrect

    • Which of the following is true with regard to the acini?

      Your Answer: Peripheral zone is least oxygenated

      Correct Answer: The central zone (Zone III) is the least oxygenated

      Explanation:

      The acini are divided into zone I (periportal), zone II (transition zone), and zone III (pericentral). Cells located close to the portal triad or peripheral zone which consist of an arteriole from the hepatic artery are the most oxygenated cells. Cells in the central zone (III) are least oxygenated and mainly receive blood supply from the central vein which is a branch of hepatic vein.

    • The transporter responsible for most glucose absorption in the lumen of the small intestine is called?

      Your Answer: SGLT 1

      Explanation:

      GLUT = Glucose transporter. GLUT are a family of proteins of different types. GLUT 1 is mainly expressed in erythrocytes, whereas GLUT 2 is mainly expressed by, liver cells and renal tubular cells. GLUT 5 is a sucrose transporter in enterocytes. SGLT- Sodium-dependent glucose cotransporter or sodium-glucose linked transporter are a family of proteins of different types. SGLT1 transporter is found in the intestinal mucosa of the small intestine and SGLT2 in the proximal tubule of the nephron.
