Question

Which hypothesis regarding the origin of life on Earth suggests that oxidation-reduction (redox) reactions may be responsible for the formation of complex organic molecules from simple organic molecules

Answer 1

The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is :

• Reducing Atmosphere Hypothesis

Reducing atmosphere

Reducing atmosphere hypothesis states that a reducing atmosphere is a condition whereby the atmosphere has an abundance of negative charges which leads to reducing reaction by the additon of electrons to compounds.

The addition of electrons to the compounds leads to the formation of complex organic molecules. some examples of reducing gases are :

• Hydrogen and
• Carbon monoxide

Hence we can conclude that The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is : Reducing Atmosphere Hypothesis.
