This medication contains digestive enzymes, which are natural substances needed by the body to help break down and digest food. Introduction. Raising the substrate concentration will raise the rate of enzyme activity up to a certain point when further increases in substrate will not increase enzyme acyivity. Enzyme Catalysis Lab. Overview Here is a collection of overall tips offered by the AP Biology Teacher Discussion Group. Try all keys with all locks and answer the following questions about Set 1 of locks. Specificity of the enzyme arises from this, only certain and specific substrates can bind to the active site, by forming weak bonds such as hydrogen bonds with the amino acids forming the active site. I referred earlier to the more obvious factors of a high effective concentration of the catalyst, exact orientation of catalytic groups, and restriction of substrate rotational freedom. Some enzymes bind metal ions to aid in catalysis. Near the tipping point. Introduction. We can learn about these transitions from studying catalysis and folding in model systems.
