Trypsinogen is split by the enzyme enterokinase to form an activated molecule of the protease trypsin. which of the following would confirm that the activation of trypsin is an example of how a positive feedback mechanism can amplify a biological process?
a. the activated trypsin enzyme can use enterokinase as a substrate
b. the trypsin produced by the reaction is capable of splitting and activating additional trypsinogen molecules
c. if levels of trypsin were to get too high, the trypsin molecules would inhibit the enzyme enterokinase
d. each mrna molecule that codes for trypsinogen can be translated repeatedly to form many peptide molecules

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna. nothing should be altered. the ph should be decreased. the temperature should be raised.
