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.

Explanation:

Cellular respiration consists of glycolysis, acetyl - CoA formation, citric acid cycle, and electron transport chain. In the electron transport chain, oxygen acts as the final electron acceptor. Hydrogen ions combine with oxygen to form water ($H_2O$), which is then released. Glycolysis and acetyl - CoA formation do not remove water from the atmosphere. The citric acid cycle mainly releases carbon dioxide ($CO_2$).

Answer:

It releases $H_2O$ to the atmosphere during electron transport.
