The following conditions were detected in a mutant cell:
a. the cell is running out of atp, while adp is building up to very high levels.
b. nadh is building up to very high levels, while the level of nad is becoming very low.
c. the amount of protons in the intermembrane space and in the matrix is becoming more equal (the strength of the proton gradient is decreasing/weakening).
d. indicate the stage of the cellular respiration process that is not functioning properly in this mutant cell.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
