What are the products of anaerobic respiration?
Answer
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:
C6H12O6→2C2H5OH+2CO2
In Lactic Acid Bacteria (Lactic Acid Fermentation):
- Lactic Acid
- ATP (Energy)
The overall reaction for lactic acid fermentation is:
C6H12O6→2CH3CHOHCOOH+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.
