chubhunter [2.5K]

<span>the soil</span>

The nitrogen used by most plants is derived from soil.

Nitrogen is an important element. It is needed by organisms to produce amino acids 

Nitrogen is made usable for plants by bacteria which change nitrogen to  ammonium.

Ammonium  gets changed to nitrates by bacteria in a process called nitrification, which takes place in soil.

A student added an enzyme to a flask containing a substrate and placed the mixture over a flame. She observed the reaction for a
expeople1 [14]
The reason should be denaturing of the active site of the enzyme.

The rate of the enzymic reaction depends on pH, concentration of substrate, enzyme molecule concentration and the temperature. With the increase of temperature, the rate of the enzymic reaction also increases.  But this only happens up to a certain point. After a certain temperature, the rate becomes to decrease and eventually will stop. This is because denaturing of the enzyme. Although other factors are perfect, the high temperature causes to break down of bond interactions and hence the active site will be changed. If the active site of an enzyme changed, then substrate cannot bind with that enzyme anymore.<span>
<span>The temperature which the rate of the reaction is maximum is called optimum temperature and it normally around 40°C. This can be varied from enzyme to enzyme</span></span>
