an experiment done to see the effect of PH on enzymes an enzyme called pepsin responsible for digesting proteins is tested 3 tubes containing egg white and pepsin with different ph for each one are incubated than tested for biuret reagent the results was tuve A ph=4.5 tube B ph=7.5 tube C ph=3.3A

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.
