Mr. Johnson is giving a lesson on enzymes in his freshman biology class. Mr. Johnson displays six beakers with either a chemical substrate or chemical enzyme in them. He tells the class that each of the substrates will spontaneously breakdown (degrade) over a set period of time. He asks the class to identify what would happen if he were able to apply the correct enzyme to the correct substrate. Which of the following is the best answer to give Mr. Johnson?

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
