Pl. help me to prepare a biology model for science fair for secondary level?

Answer 1

This my help:

Enzyme kinetics is the study of the rates of chemical reactions that are catalysed by enzymes. The study of an enzyme's kinetics provides insights into the catalytic mechanism of this enzyme, its role in metabolism, how its activity is controlled in the cell and how drugs and poisons can inhibit its activity.

Enzymes are molecules that manipulate other molecules — the enzymes' substrates. These target molecules bind to an enzyme's active site and are transformed into products through a series of steps known as the enzymatic mechanism. Some enzymes bind multiple substrates and/or release multiple products, such as a protease cleaving one protein substrate into two polypeptide products. Others join substrates together, such as DNA polymerase linking a nucleotide to DNA. Although these mechanisms are often a complex series of steps, there is typically one rate-determining step that determines the overall kinetics. This rate-determining step may be a chemical reaction or a conformational change of the enzyme or substrates, such as those involved in the release of product(s) from the enzyme

Good Luck....

Answer 2

How about making a model for showing the process of 'Germination'?
Take a deep saucer filled with soil, drop some seeds of lentils--lobiya, methi, or chana-- and sprinkle water daily.
Write down the progress that you observe every day, at the same time--say at 9 am daily. The results would be visible for you after 3-4 days.
This would demonstrate the biological process of Germination.

Answer 3

your biology model is -make natural things like birds animals in farms you know when i gave my biology test i made these things and was graded the best grade .all the best
yours

Answer 4

dear,
i dont know ur interest but i can suggest u one book 4 science projects which will b very helpfull to u.. n it is not costly...
d book is 71 science projects n publisher is pustak mahal..
it will help u a lot.
