2H+ 2H+ Respiration NADH + H+ FAD Mo5+ NO3 2x Respiration NAD+ FADH2 Mo6+ NO2 H2O FIGURE 13-16 The electrons that reduce nitrate to nitrite are brought to it by a short electron transport chain. FAD and molybdenum are actually bound to the nitrate reductase enzyme, but NADH and NAD+ diffuse between the enzyme and sites of respiration.

Metabolic pathways

Metabolism is defined as the group of life-supporting, enzyme-mediated chemical reactions in organisms. A metabolic pathway is a set of these chemical reactions that involve anabolism (synthesis of complex biomolecules) and catabolism (breakdown of biomolecules into small molecules) that occur inside a cell. Metabolites are the reacting substances, products, and intermediate substances of an enzymatic process that are altered by a series of chemical events catalyzed by enzymes.
