Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.

<u>Answer</u>:- The three forms of nitrogen in an aquarium are
1. Nitrate NO3-
2Nitrite NO2-
3. Ammonia NH3
<u>Explanation</u>:
- The waste products produced by fishes is broken down into ammonia which is highly toxic for the fishes present in the aquarium.
- The nitrogen cycle takes place in the aquarium to convert this toxic <em>ammonia</em> into lesser toxic forms.
- This nitrogen cycle proceeds to convert ammonia into <em>nitrite</em> and then nitrite into <em>nitrate</em>. This means the cycle is ammonia——>nitrite——> nitrate.
- This conversion takes place with the help of several bacteria which establish a colony in the filter bed of the aquarium in the presence of ammonia .Then these bacteria help to finally convert ammonia to nitirite and then to nitrate.
- The bacteria that convert ammonia to nitrite are oxygen loving bacteria called as <em>Nitrosomonas</em>. The nitrite so formed is less toxic as compared to ammonia.
- The conversion of nitrite to nitrate takes place by the bacterial species called as <em>Nitrobacter</em> . The nitrate thus formed is harmless for the aquarium fishes at low levels.
Thus, in this nitrogen cycle we can see that<em> there are three different forms in which nitrogen is present- ammonia, nitrate and nitrite.</em>
