The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
Hope this helps:)
Reactions involving fire are typically characterized as combustion reactions in which a material is oxidized, producing carbon dioxide, water, and carbon monoxide in some incomplete combustion reactions.
1) Mutations are caused by changes in nucleotide bases. these altered base formed different amino acid depending upon nucleotide base sequence that code specific amino acid. ... even though some mutations, can have a more effect on amino acid coding, which can affect what kind of proteins are produced.
your welcome :)
It depends on whatever it's real or just a simple theory. But, at times it may not be simple as it seems, because theories are often left as theories. In the near future (or even now) they'll be testing to see if theories can be proven as a fact!
Good luck!
