| 1. | The cortex is what makes the endospore so resistant to temperature.
|
| 2. | Small acid-soluble proteins ( SASPs ) are found in endospores.
|
| 3. | The dipicolinic acid helps stabilize the proteins and DNA in the endospore.
|
| 4. | The heat resistance of endospores is due to a variety of factors:
|
| 5. | Germination involves the dormant endospore starting metabolic activity and thus breaking hibernation.
|
| 6. | It is implicated as responsible for the heat resistance of the endospore.
|
| 7. | Dipicolinic acid forms a complex with calcium ions within the endospore core.
|
| 8. | Endospores possess five times more sulfur than vegetative cells.
|
| 9. | Endospores can stay dormant for a very long time.
|
| 10. | For instance, endospores were found in the tombs of the Egyptian pharaohs.
