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 are aerobic respiration and anaerobic respiration.^[1]

[edit] Aerobic respiration

Main article: Aerobic respiration

When in the presence of oxygen, cells use aerobic respiration to obtain energy from glucose molecules.^[2][3]

Simplified Theoretical Reaction: C₆H₁₂O_{6 (aq)} + 6O_{2 (g)} → 6CO_{2 (g)} + 6H₂O _(l) ΔH_c -2880KJ

In aerobic respiration, the cellular waste products are:

• carbon dioxide (CO₂)
• water (H₂O)

[edit] Anaerobic respiration

Main article: 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 2C₃H₆O₃ + 2 ATP (120 kJ)

In anaerobic respiration, the cellular waste product is:

• Lactic acid (C₃H₆O₃)
