If a scientist carried out a growth experiment on a prokaryote in media without a nitrogen source you would expect:

Question

Accepted Answer

∻Answer∻ ⚹ The scientist would observe no growth or an initial lag in growth followed by a very slow growth rate if the prokaryote can fix atmospheric nitrogen. ⚹ ∻Solution∻ ‖ a ⋮ Nitrogen is essential for growth: Nitrogen is a critical element for the synthesis of amino acids, nucleic acids, and other cellular constituents. ‖ ‖ b ⋮ Lack of nitrogen source leads to no growth: In a medium without a nitrogen source, a prokaryote that cannot fix nitrogen from the atmosphere will not grow because it cannot synthesize the necessary cellular components. ‖ ‖ c ⋮ Nitrogen-fixing prokaryotes: Some prokaryotes can fix atmospheric nitrogen ($N_2$) into a usable form (ammonia, $NH_3$) through nitrogen fixation. If the prokaryote in the experiment can fix nitrogen, it may show slow growth after an initial lag phase. ‖ ∻Key Concept∻ ⚹ Nitrogen is essential for prokaryotic growth ⚹ ∻Explanation∻ ⚹ Without a nitrogen source in the growth media, a prokaryote will either not grow or, if capable of nitrogen fixation, grow very slowly after adapting to the conditions. ⚹◊What metabolic process would be affected in the absence of a nitrogen source in the growth media for the prokaryote?⍭ Generate me a similar question◊
