Basis Of Differentiation | Intracellular Enzymes | Extracellular Enzymes |
Definition | Are enzymes that are produced and retained inside the cell to be used within the cell itself | Are enzymes that are produced by the cell and released outside of the cell into the extracellular space for external use |
Also Known As | Endoenzymes | Exoenzymes |
Location | May be found unbound in the cytoplasmic fluid or bound to specific organelles such as ribosomes, mitochondria, or nucleus | Found in the extracellular fluid outside in tissue spaces, body fluids such as saliva and blood, or organ cavities such as intestine and stomach |
Activity | Function within the cell | Function outside the cell |
Functions | - Protein synthesis | |
Mechanism of action | Break large polymer into small chains of monomer | Break lark polymer into small chain of monomer one at a time |
Type of digestion | Undergo intracellular digestion | Undergo extracellular digestion |
Involvement | Are responsible for the digestion of food particles inside the cytoplasm of unicellular organisms | Are responsible for the digestion of food inside the alimentary canal of higher animals and the extracellular digestion in decomposers such as bacteria and fungi |
Proportions | Account for the majority of enzymes | Account for the minority of enzymes |
