Pick a digestive enzyme. Draw a diagram to show the activity of that digestive enzyme on the appropriate polymer. (ex. Sucrase, Amylase, Trypsin, Lipase, Pepsin)
In your diagram label: enzyme, substrate, active site

In a particular chemical reaction, the energy of the reactants is 30 kj and the energy of the products is 5 kj. 
 the maximum energy of the system is 40 kj. sketch a potential energy diagram for this reaction. make sure to label the energy of the reactants, the energy of the products, the activation energy, and the enthalpy change for the reaction.
