The pancreas will secrete two types of enzymes into the duodenum, functional and non-functional. non-functional ones have to be non-functional otherwise they will digest the pancreas on their way out. functional ones are able to enter the duodenum and immediately start working. which of the following enzymes are non-functional and require some sort of modification before they are able to aid in digestion.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
