One of the "triggers" proposed for the Cambrian explosion is a dramatic rise in oxygen concentrations that occurred in the ocean
ZanzabumX [31]

Answer:

1. Oxygen is an effective final electron acceptor in cellular respiration because of its high electronegativity.

2. Organisms that use it as a final electron acceptor can produce more usable energy than organisms that do not use oxygen, but only if it is available.

3. With more available energy, aerobic organisms can grow larger and move faster.

Explanation:

1. Cellular respiration is an aerobic pathway because oxygen is an electron acceptor. This process produces 38 molecules of ATP per glucose. The atomic elements that are positioned at the right of the periodic table have high electronegativities because they tend to be electron acceptors.  

2. The efficiency of energy production of aerobic respiration is much higher compared to the anaerobic respiration because this metabolic pathway (aerobic respiration) can produce 38 molecules of ATPs per glucose molecule, while anaerobic respiration produces only 2 ATPs by glucose.

3. A higher amount of available energy improves the metabolic profile of the organisms with aerobic respiration.
