Capitolo 5, Problema 6

Three common inorganic electron acceptors in anaerobic respiration are _______,_______, and _______.

Guida verificata passo dopo passo
1
Understand that anaerobic respiration uses electron acceptors other than oxygen to generate energy in the absence of oxygen.
Recall that common inorganic electron acceptors in anaerobic respiration include molecules that can accept electrons during the electron transport chain process.
Identify the three most common inorganic electron acceptors: nitrate (NO3^-), sulfate (SO4^{2-}), and carbon dioxide (CO2).
Recognize that nitrate is reduced to nitrite or nitrogen gas, sulfate is reduced to hydrogen sulfide, and carbon dioxide is reduced to methane in different microbial processes.
Summarize the answer by listing the three inorganic electron acceptors as nitrate, sulfate, and carbon dioxide.

Electron Acceptors in Anaerobic Respiration

In anaerobic respiration, inorganic molecules such as nitrate, sulfate, and carbon dioxide serve as electron acceptors, allowing microbes to transfer electrons and produce energy in oxygen-free environments.

Role of Inorganic Electron Acceptors

Inorganic electron acceptors like nitrate (NO3-), sulfate (SO4 2-), and carbon dioxide (CO2) enable microbes to sustain energy production by accepting electrons during the electron transport chain in the absence of oxygen.
