Carrier ions like Na+ facilitate the absorption of substances like
Fructose and some amino acids
The correct option is A Amino acids and glucose
Most ions are actively absorbed along the length of small intestine. The absorption of Na+ is coupled with absorption of glucose and amino acids. Glucose and galactose are taken into the enterocyte by cotransport with sodium using the same transporter. Fructose enters the cell from the intestinal lumen via facilitated diffusion through another transporter. Fatty acids are combined with proteins within the cells and resulting chylomicrons are extruded. They enter lacteals and are transported to the circulation via lymph.
