a) The main class of enzymes that digestproteins are known as_______________. Endopeptidases causes bondsto break in the middle/end of peptides.Exopeptidases are important for cleaving off the terminal aminoacids. For C-terminal amino acids _________-peptidases will be usedwhile _________ -peptidases will cleave N-terminal amino acids.Examples of such enzymes are pepsin, which requires analkaline/acidic environment in the _______________in order to be functional, and _______________, found in pancreaticsecretions, which requires an _______________ environment.
b) Ghrelin is an(orexigenic/anorexigenic) hormone. Its levels inthe blood are (increased/decreased) during timesof fasting or hypoglycemia and(increased/decreased) when blood glucose and aminoacid levels are high.
