Enzymes are required for many metablic reactions to take place because the cellular environments are often not ideal for the reactions to occur spontaneously. Metabolism in an organism involves many different types of reactions so require many different types of enzymes which facilitate specific reactions (enzymes are very specific). These enzymes can be activated and inhibited by specific molecules, but this is also specific to the enzyme and the reaction that specific enzyme controls.

There is no simple answer to your question but I hope this helps.

thank you so much


i have one last question



-plan an experiment to investigate how different catalysts affects the rate of a reaction.


this is about catalysts and enzymes...

It is worth noting that enzymes are biological catalysts. The first reaction that springs to mind when thinking of school experiments is the breakdown of hydrogen peroxide to give water and oxygen. In the body, this reaction is catalysed by the enzyme 'catalase'.

In order to investigate your experimental question, you would need to use many other catalysts for this reaction as well and compare the different rates at which the breakdown od hydrogen peroxide takes place in the presence of the different catalysts.

I have found a useful paper on this:
http://www.rsc.org/learn-chemistry/r...id=CMP00002415

The paper in the url is an experiment you could use to answer your question. If you look under the 'chemicals' section, there is a list of chemicals which catalyse the breakdown of hydrogen peroxide other than catalase (note: the 'liver' and 'potato' both contain catalase which acts as the catalyst).

Hope this helps!
