3 Speeding things up

1

a     a)  A catalyst will speed up or slow down a reaction  but is not changed itself

b)         b)Living organisms make very efficient catalysts know as enzyme

c)          c)All enzymes are made of protein.

d)          d)the reaction that take place in your cells wouldn’t happen fast enough to keep you alive without enzyme

e)           e)Digestive enzymes break down large food molecules into smaller ones .

f)       each type of enzyme break down a specific type of molecules

2    a) They work best when the product is acid

       b) They work best when the product is neutral

       c)

3    a) the amylase destruct the starch, because iodine turn blue-black in the presence of starch

      b) The amylase takes more time to destruct the starch at room temperature.

      c) For seeing if the witness of the starch will be destruct at room temperature.

      d) If the mixture is more acid so the enzyme will not destroy the starch.
