What are the products of anaerobic respiration?

The products of anaerobic respiration vary depending on the organism and the type of anaerobic process occurring. Here are some common examples:

In Yeast (Alcoholic Fermentation):

• Ethanol (Alcohol)
• Carbon Dioxide (CO₂)

The overall reaction for alcoholic fermentation in yeast is:

C6​H1​2O6​→2C2​H5​OH+2CO2​

In Lactic Acid Bacteria (Lactic Acid Fermentation):

• Lactic Acid
• ATP (Energy)

The overall reaction for lactic acid fermentation is:

C6​H1​2O6​→2CH3​CHOHCOOH+2ATP

In Other Anaerobic Respiration Processes:

• Sulfate Reduction: Produces hydrogen sulfide (H₂S) when sulfate (SO₄²⁻) is used as the terminal electron acceptor.
• Nitrate Reduction: Produces nitrogen gases (N₂ or N₂O) when nitrate (NO₃⁻) is used as the terminal electron acceptor.
• Methanogenesis: Produces methane (CH₄) in methanogenic bacteria.

Each type of anaerobic respiration has distinct products based on the specific metabolic pathways and the electron acceptors used.
