Are there other chemical reactions that pepsin can catalyze

The specific reaction catalyzed by pepsin is the acid hydrolysis of the peptide bond. This reaction will break down proteins into smaller units to enable the digestive process. Pepsin demonstrates an unusual property for an enzyme; it does not actually form chemical bonds with its substrate.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
