Question
The process of converting proinsulin into mature insulin involves: (1 Point)a) Cleaving off the C-peptide segmentb) Adding a signal peptidec) Attaching disulfide bondsd) All of the above
Solution
The process of converting proinsulin into mature insulin involves:
a) Cleaving off the C-peptide segment: This is correct. The C-peptide is a part of proinsulin that is removed during the conversion process to create mature insulin.
b) Adding a signal peptide: This is incorrect. The signal peptide is already present in preproinsulin, the precursor to proinsulin. It is not added during the conversion of proinsulin to insulin.
c) Attaching disulfide bonds: This is correct. Disulfide bonds are formed during the conversion process to create the mature insulin structure.
Therefore, the correct answer is not "d) All of the above" because not all statements are correct. The correct answer is a combination of a) and c).
