e
Endopeptidases cleave amino acids off the ends of polypeptides
QuestionChoice
Amino acids are absorbed through facilitated diffusion and co-transport. Amino acids are absorbed alongside Na+, while peptides can be co-transported with H+.

c
Amino acids are absorbed alongside H+ across the intestinal brush border
QuestionChoice
In the duodenum, peptide digestion occurs at the brush border, intestinal lumen and intracellularly.

b
Peptide digestion only occurs at the brush border of the duodenum
QuestionChoice
Pepsinogen is secreted from chief cells in the stomach body. Secretion is activated by HCl release from parietal cells, which is stimulated by parasympathetic and enteric nerve activity.
