$NH_3$ and $CO_2$

Vedclass · Answer

(B) Chemosynthetic autotrophs,such as nitrifying bacteria (e.g.,$Nitrosomonas$),obtain energy by oxidizing inorganic substances like ammonia $(NH_3)$ or nitrites $(NO_2^-)$.This energy is then used to fix atmospheric carbon dioxide $(CO_2)$ into carbohydrates through a process similar to the Calvin cycle.Therefore,the raw materials for carbohydrate synthesis in these bacteria are $CO_2$ and $H_2O$ (as a source of hydrogen),while the energy is derived from the oxidation of $NH_3$ or $NO_2^-$. Among the given options,$NH_3$ and $CO_2$ represent the essential substrates involved in their metabolic pathway.
