Answer:
c. A single enzyme typically reacts with many different substrates.
Explanation:
Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.
Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.

<em>All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA. But the main common feature that is most talked about it Cytoplasm and Ribosomes. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particles suspended in it. Ribosomes, the organelles on which protein synthesis takes place.</em>
Hope this helps, have a good day. c;
