According to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), clinical manifestations of posttraumatic stress disorder must be present for how long for a diagnosis to be made?

What can you conclude from this experiment? 

Explain your results for Test tube E1. How did the enzyme concentration influence the height of bubbles that were produced?

Explain your results for Test tube E3. How did the enzyme concentration influence the height of bubbles that were produced?

Part 3: Effect of Enzyme Concentration in Enzyme Activity  At a constant enzyme concentration and at lower concentrations of substrates, substrate concentration is the limiting factor. As the substrate concentration increases, the enzyme reaction rate increases. However, at very high substrate concentrations, the enzymes become saturated with substrate and a higher concentration of substrate does not increase the reaction rate. 

What is the optimum pH for your enzyme to function?
