The Energy-Yielding Process of ________ Occurs Only in the Archaea

Question

The energy-yielding process of ________ occurs only in the archaea.
A) fermentation
B) sulfur oxidation
C) hydrogen oxidation
D) methanogenesis
E) anaerobic respiration

Accepted Answer

Methanogenesis is a unique energy-yielding process that only occurs in the archaea, specifically in methanogenic archaea. This process involves the production of methane gas as a byproduct of the breakdown of organic matter under anaerobic conditions. The other options listed (fermentation, sulfur oxidation, hydrogen oxidation, and anaerobic respiration) occur in a variety of microorganisms, including bacteria and some archaea.
