Bread is a carbohydrate, digestive salivary amylase breakdown bread into sugars.
Therefore, digestion begin from the mouth and it contain saliva which comprises of the enzymes.
Answer: The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy.
A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.
