Question

All cells in multicellular organisms contain thousands of different kinds of enzymes that are specialized to catalyze different chemical reactions. Given this information, which of the following is most likely to be true? All cells do not contain the same types of enzymes. All cells contain exactly the same number of enzymes. All cells contain exactly the same types of enzymes. All cells do not contain enzymes.

Answer 1

I believe it to be *All cells do not contain the same types of enzymes*. Well it said "All multicellular organisms contain thousands of DIFFERENT kinds of enzymes".

Answer 2

 Different enzymes have specific active sites which can only catalyze one substrate. Enzyme-substrate complexes are produced only when the substrate fits into the active site :)
