Trypsin and pepsin are both enzymes in the digestive system which catalyze the breakdown of proteins in food into smaller peptide chains or into individual amino acids. However, like other enzymes, they differ in their substrate and optimal conditions. Analyze the
graph and select ALL of the statements that accurately describe the action of trypsin and pepsin.

A)
Trypsin has an optimal pH of 8.
B)
Pepsin works best at a pH of 3.
Both enzymes have an optimal pH of 7
D)
Pepsin works best in more acidic conditions.
E)
Trypsin works best in more acidic conditions,

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
