Enzymes are catalysts. This means that they are able to speed up chemical reactions. Which of the following statements is also true of enzyme catalysts?
since you have not given the complete question, my guess would be that IT INCREASES THE CHEMICAL REACTION RATE AND DECREASES THE ENERGY GIVEN OFF. The "AND DECREASES THE CHEMICAL ENERGY GIVEN OFF" could be removed because some resources (i.e textbooks) dont have that part.
....and the options are?
