Question

What role does cellular respiration play in the water cycle?

It removes H2O from the atmosphere during glycolysis.
It removes H2O from the atmosphere during acetyl CoA formation.
It releases H2O to the atmosphere during the citric acid cycle.
It releases H2O to the atmosphere during electron transport.

Answer 1

the answer would be D 

Answer 2

The right answer is It releases H2O to the atmosphere during electron transport.

Respiration was defined following Lavoisier's work as a mode of gaseous exchange by which a living being releases carbon dioxide in exchange for an absorption of oxygen.

It is usually the oxygen of the air that intervenes: activated, it will combine with protons to form the metabolic water excreted during breathing in the atmosphere.
