The chemistry of life as we know it relies heavily on carbon-bearing molecules and compounds and catalytic actions among these materials. Catalytic processes involving carbon compounds may serve as potential biosignatures.
There exist abiotic catalysis reactions with organic carbon that occur at identical speed and have the same product formation as biological carbon oxidation and oxygen gas formation. [Claire Elbon][Congruence, General] Environments
Superoxide will decompose to hydrogen peroxide that reacts with water to produce oxygen gas (O2) and carbon dioxide (CO2)
Abiotic catalysis reactions identical to biological carbon oxidation and oxygen gas formation require external activation energy (e.g., heat, UV-radiation), extremely high volumes of reactants, or other highly specific conditions. [Claire Elbon] [Congruence, General]Environments
Hydrogen peroxide does not accumulate, or survive under Martian surface conditions
The compounds and conditions needed for abiotic catalysis reactions with organic carbon are common in extraterrestrial sites. [Claire Elbon] [Congruence]Environments
Life detection methods used to ensure abiotic conditions are often not robust enough. [Claire Elbon][General] Environments
Mars analog soil testing in the Atacama did not match the conditions of the Mars Viking LR experiments.
