Answer
Correct Answer: Proteins
Explanation
Given data & pathway
- Plants take up nitrate (NO3−) from soil.
Concept/ApproachNitrate is reduced to nitrite (NO2−) and then to ammonium (NH4+), which is incorporated into amino acids. Amino acids are then polymerized to form proteins.
Key stepsNO3− → NO2− → NH4+ → amino acids → proteins
Final AnswerProteins.
