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

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
