Control of Cellular Metabolism
Cellular Response to Environment Is Complex
Despite being able to visualize and analyze living cells under the microscope in real time, scientists are still challenged by the fact that cells are ALIVE, and they respond to their environment dynamically.
Cellular metabolism requires an exchange of not only vital nutrients but of gases such as oxygen and carbon dioxide. Cellular waste products must be removed and fresh materials replenished. Many living cells including mammalian and microbiota cells are typically not robust organisms. Many cell types do not tolerate unfavorable conditions for extended periods. In addition, affected cells may modify their behavior to adapt to their changing micro-environment often without the experimenter being aware of the changes.
