It is unchanged and can be used again for the same chemical reaction.
Explanation:
Enzymes are bio-catalysts which speed up the rate of chemical reactions by <u>lowering the activation energy</u> for the reaction and <u>producing binding energy</u>. But during chemical reaction the enzymes are unchanged and can be reused for the same chemical reaction. Most of the enzymes are proteins and without enzymes a biochemical reaction cannot take place.
For example: Amylase catalyzes the conversion of starch into sugar.
One thing that a scientist might ask about the movement of carbon dioxide through the whale and its surrounding is “how did the whale get the carbon dioxide?”. Another thing that a scientistmay ask about this is “how does the carbon dioxide affect the ecosystem?”
