- Cellular waste product
Cellular waste products are formed as a byproduct of
cellular respiration , a series of processes and reactions that generate energy for the cell, in the form of ATP. Two examples of cellular respiration creating cellular waste products areaerobic respiration andanaerobic respiration . [ [http://www.answers.com/topic/cellular-respiration?cat=health cellular respiration: Definition and Much More from Answers.com ] ]Aerobic respiration
When in the presence of oxygen, cells use aerobic respiration to obtain energy from
glucose molecules. [ [http://www.purchon.com/biology/aerobic.htm Aerobic Respiration ] ] [ [http://library.thinkquest.org/C004535/aerobic_respiration.html Aerobic Respiration ] ]Simplified Theoretical Reaction: C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O (l) ΔHc -2880KJ
In aerobic respiration, the cellular waste products are:
*carbon dioxide (CO2)
*water (H2O)Anaerobic respiration
When oxygen is not available, a cell must undergo anaerobic respiration to generate energy. Fermentation is an example of anaerobic respiration.
Simplified Theoretical Reaction: C6H12O6 o 2C3H6O3 + 2 ATP (120 kJ)
In anaerobic respiration, the cellular waste product is:
*Lactic acid (C3H6O3)References
