Could some help me with my English with this info? and Tell me how I could
improve it?

The results truned out the way they did because the tests that were done in
two of the experiments, tow conditions that affect an enzyme's shape wre
used wihc were pH and temperature. The pH affected enzyme activity because
of the different levels of pH used. The pH that was calculated as the
constant was neutral at seven. The differences outside the constant were a
result of the different pH levels used. Temperature afffects enzyme activity
because as the temperature is increased the reat of enzyme activity
increases, but at 37 degrees there is a constant met that shows the most
significant increases in the enzyme actvity if heated too much there is very
little enzyme activity because the constant has been exceeded and too much
heat is used and this affects the enzyme's activity.

In two of the other experiments other materials were used that affect the
reate of enzymatic reaction which are enzyme activity because test tubes two
and three were found to be the constant and, as the extract was increased
which contained the enzyme the level of enzyme activity increased. This
means that even though as the extract increases the enzyme concentration
effects the amount of enzyme activity, the constant has been exceeded. In
the experiment of denaturation the extract that was used in text tubes two
and three contained the enzyme and no denatured enzyme was used so there
could be no effect to how quickly the enzyme increased. In test tubes four
and five there were no extract used but a dnatured enzyme was used which
contains very little enzymes because of the denaturing in that enzyme. This
affects enzyme activity because the denaturing effect how many enzymes are
used. The inhibitor used was hydroxylamine which is a competitive inhibitor.
In test tubes tow and three there were an extract used which contains the
enzymes but there was no inhibitor used, this lets the enzyme activity
increase because the enzyme active site was no blocked by the inhibitor. In
thest tubes four and five there were hydroxylamine and extract. The enzyme
actvity increased very little because the hydroxylamin blocked the active
sites of the enzyme present.

The reason the results turned out as expected is because of the conditions
that effect the enzyme's shape such as pH and temperature; othere materials
available such as enzyme concentration and denaturation. Also the action of
an inhibitor affects enzyme activity. This results will occur if the above
conditions are used becuase they all affect how an enzyme functions and this
will affect how much and who enzyme activity will occur.
