1. Sketch a graph to predict the concentration of substrate in a reaction over time with time on the x-axis and amount of substrate on the y-axis. 

2. Sketch a graph to predict the concentration of product over time with time on the x-axis and amount of product on the y-axis. 

3. Given the two graphs , how would the rate at which the enzyme converts substrate into product be determined? (Hint: think about the concentration of reactants in a period of time, like 'miles per hour')

Enzymes speed up the rate of chemical reactions. Enzyme Substrate Product
