For the following questions we will be exploring enzyme mechanism and regulation through a family of proteases called the caspases.

Proteases are enzymes that hydrolyze peptide bonds in their protein substrates. Which of the following functions for proteases were discussed in the Enzyme II lectures? Protease can be used… (choose all that apply)

a. by viruses such as HIV and COVID to cut one long peptide chain into individual proteins needed by the virus to function
b. by the insulin receptor in our cells to release bound insulin hormone peptides
c. in our cells during translation to build-up proteins from individual amino acids
d. in our digestive system to break down consumed proteins to get amino acids
