The pancreatic enzymes trypsin, chymotrypsin, and elastase all hydrolyze peptide bonds on the carbonyl side of several different amino acids in a protein. What term best describes their enzyme specificity

the term that best describes their group specificity is group-specific.    

Explanation:

These enzymes are group-specific because their specificity is on catalyzing a particular functional group present in some proteins. In this case, the enzymes are group-specific due to the fact that they hydrolyze peptide bonds by acting on the carboxyl group of the amino acid.    

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
