Question

All types of methanogenesis are poisoned by ________ and therefore require extreme ________.
A) carbon dioxide; aerobiosis
B) oxygen; anaerobiosis
C) heat; cold
D) pressure; vacuum
E) high salinity; freshwater

Accepted Answer

Methanogenesis is an anaerobic process, meaning it occurs in the absence of oxygen. All types of methanogenesis are poisoned by oxygen and therefore require extreme anaerobiosis. Option A is incorrect as carbon dioxide is actually a source of carbon for methanogens. Option C, D, and E are also incorrect as they are not related to methanogenesis.
