Nucleic acid digestion yields nucleotides, whereas protein digestion yields amino acids; both digestive processes nucleic acid digestion yields nucleotides, whereas protein digestion yields amino acids: a) both digestive processes are catalyzed by the same enzyme. b) require the presence of hydrochloric acid to lower the ph. c) add a water molecule to break bonds (hydrolysis). d) require atp as an energy source.

B

Explanation:

Nucleic acid digestion yields nucleotides, whereas protein digestion yields amino acids. Both digestive processes require the presence of Hydrochloric acid to lower the pH.  Hydrochloric acid popularly described as HCl contributes in both protein and nucleic acid digestion by supplying hydrogen ions which in turn activate pepsinogen, which in turns form pepsin necessary for digestion.
