Here are some key features of DNA polymerases:<span>They can only add nucleotides to the 3 end of a DNA strandThey can't start making a DNA chain from scratch but require a pre-existing chain or short stretch of nucleotides called a primerThey check their work, removing the vast majority of "wrong" nucleotides that are accidentally added to the chain</span>
Generally speaking, enzymes (which amylase happens to be) do not undergo any permanent structural change while carrying out their function. Some do exhibit transient conformational change during a reaction, but upon completion regain their original form.
So your initial assumption is correct: once amylase has finished catalyzing the breakdown of starch into less complex sugar molecules, it moves on and repeats the process over and over.
I think the EAR is 7.79%
Since EAR = e^0.75 -1
= 7.79%
<span>C.Enough supporting evidence has accumulated for it to be called a theory.
Hope this helps!</span>
