Extracellular Enzymes Intracellular Isolate Explain Tend Biotechnology Secreted

Extracellular enzymes are secreted, making them easier to isolate and use. Microorganisms produce few extracellular enzymes, simplifying identification compared to the hundreds of intracellular ones. Additionally, extracellular enzymes are more robust to variations in temperature and pH.

Enzimi ekstraselulari sunt secretaţi, aşa că sunt mai uşor de izolat şi utilizat. Fiecare microorganism produce puţini enzimi extracelulari, făcându-i mai uşor de identificat, spre deosebire de sutele de enzimi intracelulari. Enzimi extracelulari sunt, de asemenea, mai rezistenţi la variaţii de temperatură şi pH.

Front Explain why extracellular enzymes tend to be used more than intracellular in biotechnology.
Back Extracellular vs intracellular:
  • Extracellular are secreted - easier to isolate and use
  • Each microorganism produces few extracellular enzymes - easy to identify and isolate required enzyme vs hundreds of intracellular
  • Extracellular are adapted to cope with greater variations in temp and pH because conditions outside cells are less tightly controlled than inside
