- The Mechanism of Action of Cyclophosphamide and its toxicity reference :http://dx.doi.org/10.3390/scipharm88040042 (reseach paper DOI plz answer in detail do not give short answer )1. The optimal conditions for salivary lysozyme (hydrolyzing glycoproteins ofbacterial wall) are 37 C- temperature and pH is 5.2. Explain the decrease in this enzyme activity if the temperature will rise up to 60 °C and pH will be changed to 8.0. To answer the question: a) draw the graph of the velocity dependency on temperature and pH; b) calculate the relative enzyme activity if 10 mg of lysozyme catalyzes the formation of 5 uM of the product per 2 minutes. 2 Consider the matic reaction schee: Asnaragine + H20 Aspartate+ NH3:1) 4 ms. Name an enzyme that requires NAD/NADH for activity. Draw the chemistry of this reaction (show mechanism).
