In the process of atmospheric nitrogen fixation in leguminous plants, ammonia is the initial stable product. A single nitrogen molecule is converted into two ammonia molecules, requiring 16 ATP molecules, an electron donor like ferredoxin, a hydrogen donor such as NADPH or FMNH2, and the nitrogenase enzyme. Which of the following statements is accurate?

1. Ammonia is the initial stable product formed during nitrogen fixation in leguminous plants.
