10 Questions
What facilitates the transport of amino acids into the portal vein?
Na+ independent transporters
What is the dependence of one of the symporters involved in the absorption of amino acids?
H+ dependent
What type of transport systems are used for the absorption of free amino acids and di- and tripeptides?
Active transport systems
What is the location of the active transport systems involved in the absorption of amino acids?
Enterocyte membrane
What is similar between the absorption of glucose and amino acids?
Active transport systems
What is the role of Na+ in the absorption of free amino acids and di- and tripeptides?
Na+ is involved in the symport mechanism of amino acid transport
What is the primary function of the enterocyte membrane in amino acid absorption?
To facilitate the transport of amino acids into the portal vein
What is the difference between Na+ dependent and H+ dependent symporters?
Na+ dependent symporters use a different ion to facilitate transport
What is the significance of di- and tripeptides in amino acid absorption?
They are absorbed along with free amino acids using specific transport systems
What is the fate of the absorbed amino acids?
They are transported into the portal vein
Learn about the absorption of amino acids and peptides in the enterocyte membrane, including the role of Na+ and H+ dependent transporters and symporters. Understand how amino acids are transported into the portal vein.
