Mode of action of enzymes — practice question

Prokaryotes and eukaryotes both make extracellular enzymes. In the external surroundings of some prokaryotes, extracellular digestive enzymes are present. When phagocytosis occurs in eukaryotic cells, hydrolytic enzymes digest some prokaryotes. Which row indicates the places where extracellular enzymes are made?

  • Adigestive enzymes used by prokaryotes: inside cells; hydrolytic enzymes used by eukaryotic phagocytes: inside cells
  • Bdigestive enzymes used by prokaryotes: inside cells; hydrolytic enzymes used by eukaryotic phagocytes: outside cells
  • Cdigestive enzymes used by prokaryotes: outside cells; hydrolytic enzymes used by eukaryotic phagocytes: inside cells
  • Ddigestive enzymes used by prokaryotes: outside cells; hydrolytic enzymes used by eukaryotic phagocytes: outside cells
