Can someone help me with these enzyme lab problems?
1. Which substrate(s) does tyrosinase act upon best?
2. Does tyrosinase exhibit a high level of specificity?
3. Does tyrosinase appear to exhibit absolute specificity (i.e. catalyze only one reaction) or group specificity (i.e. catalyze the reaction of a structurally related group of substances)?
4. What is the difference in inhibitory activity between resorcinol, benzoic acid, and phenylthiourea?
5.Phenylthiourea has a strong affinity for copper.
-a Draw the structure of phenylthiourea and indicate which portion of the molecule binds to copper?
-b Would you conclude that copper is located at the active site of tyrosinase?
5)Explain why there is decreased enzyme activity at 0 degrees celsius and also 70 degress celsius
a- Do enzymes differ from chemical catalysts with regard to temperature?
