Looking at Figure 5 above, how is the enzyme similar to a lock and a key? 6. Complete the following analogy using the terms show in figure 5 (Enzyme and Substrate). 7. If the substrate in the first image in the left of the series is a disaccharide such as sucrose, what is the enzyme doing to the disaccharide? 8. The picture above is showing what is known in biochemistry as the "lock and key theory." Explain why you think this theory is used to describe enzymes.Please handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.
