Task: Question Generation
Input (English): Background Paragraph: An enzyme is a protein that acts as a biological catalyst. Recall that a catalyst is a substance that increases the rate of a chemical reaction without itself being consumed in the reaction. Cellular processes consist of many chemical reactions that must occur quickly in order for the cell to function properly. Enzymes catalyze most of the chemical reactions that occur in a cell. A substrate is the molecule or molecules on which the enzyme acts. In the urease catalyzed reaction above, urea is the substrate. The Figure below diagrams a typical enzymatic reaction. 
Story: Robert is a scientist that is analyzing the skin cells he obtained from a new species of spider. He is comparing two cells side by side. He notices that the cell on the left, cell A, does not have any enzymes present. The cell on the right, cell B, however contains a large number of enzymes.
Output (English): Which cell will have faster chemical reactions?
