Fungus (1333 words) |
 | Fungi are heterotrophic, that is they get their energy by breaking down organic molecules, and cannot synthesize organic molecules from inorganic substances like plant s. |
| They feed by secreting exoenzyme s into the surrounding substrate. |
| Exoenzymes act like the digestive enzyme s of animal s, breaking apart large organic molecules, but function outside the organism. |
| Exoenzyme - Wikipedia, the free encyclopedia (80 words) |
| An exoenzyme, or extracellular enzyme, is an enzyme that is secreted by a cell and that works outside that cell. |
| It is usually used for breaking up large molecules that would not be able to enter the cell otherwise. |
| The opposite of an exoenzyme is called an endoenzyme. |
