Question

Reduced inorganic compounds can serve as an _______________ to an ETS with a terminal ________________ acceptor that is a strong _______________.

a) Electron carrier, oxygen, oxidizing agent
b) Oxygen, electron carrier, reducing agent
c) Electron acceptor, oxygen, reducing agent
d) Electron donor, oxygen, oxidizing agent

Answer 1

Reduced inorganic compounds can serve as an electron donor to an ETS with a terminal electron acceptor that is a strong oxidizing agent.

Step-by-step explanation:

In aerobic respiration, reduced inorganic compounds can serve as an electron donor, oxygen, reducing agent to an ETS with a terminal electron acceptor, oxygen that is a strong oxidizing agent.

For example, in aerobic respiration, the final electron acceptor at the end of the electron transport chain is an oxygen molecule that becomes reduced to water. This process involves the transfer of electrons from reduced inorganic compounds (electron donor) to oxygen (electron acceptor), and oxygen acts as a strong oxidizing agent.

Overall, the correct answer is: d) Electron donor, oxygen, oxidizing agent.
