Compare the production of N₂ gas by denitrification and anammox. Are they both aerobic processes? What are the implications for a given pool of NO₂^– and NO₃^–?

Expert Solution

Summary Introduction

To compare: The production of N₂ gas by denitrification and anammox and to find whether these two processes are aerobic.

Introduction: The biogeochemical cycle through which nitrogen is transformed into various chemical forms (as it circulates between the marine ecosystem, terrestrial, and the atmosphere) is known as the nitrogen cycle. In the environment, a wide variety of nitrogen is present in a variety of chemical forms. This includes nitrite (NO₂), organic nitrogen (N), nitrous oxide (N₂O), ammonia (NH₄⁺), nitric oxide (NO) or inorganic nitrogen gas (N₂), and nitrate (NO₃).

Explanation of Solution

Denitrification: It is an anaerobic process in which nitrogen gas is generated from nitrate.

Anammox: It is also an anaerobic process in which nitrogen gas is generated, but ammonia is oxidized by using nitrite as the terminal electron acceptor.

Summary Introduction

To describe: The implication for a given pool of NO₂ and NO₃_.

Explanation of Solution

The implications of both the reactions include a loss of ammonium, nitrate, and nitrite from a system as the generated nitrogen gas gets distributed into the atmosphere.

One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?
