At the End of Cellular Respiration, Oxygen Combine with Electrons

question 71

Multiple Choice

At the end of cellular respiration, oxygen combine with electrons of a very low energy level. How are the specific properties of oxygen beneficial to the organism that uses it as a final electron acceptor? ​

• A)Oxygen is highly reactive and readily accepts electrons.
• B)Oxygen is strongly electronegative and helps pull the electrons through the electron transport chain.
• C)Oxygen allows a maximum output of energy for ATP synthesis.
• D)Oxygen is the only molecule that can act as a final electron acceptor.
• E)Oxygen is highly reactive and readily oxidizes methane.

Definitions:

Hot Spots

Volcanically active areas located usually in the middle of tectonic plates, characterized by hot magma rising from deep within the Earth's mantle.

Volcanically Active

Refers to a geographic area where volcanoes can erupt, showing signs of seismic, geothermal, or eruption activity.

Island Chains

Island chains are series of islands formed from similar geological processes, such as volcanic activity, and are often found stretching across regions of the ocean.

Back-arc Seafloor Spreading

The process of seafloor spreading occurring behind an oceanic trench associated with subduction zones, leading to the formation of new oceanic crust.
