Explain how an enzyme lowers the required energy of activation for a reaction. 1. What are enzymes? 2. What are their main properties? 3. Write an experiment to demonstrate the effect of temperature on enzyme reaction. What is a detailed chemical explanation for ho...
Transport properties of molten salt coolants ensure efficient cooling with natural circulation; the salt–wall heat transfer coefficient is close to the same coefficient for water. The thermal diffusivity of the salt is 300 times smaller than that of sodium. Therefore, all other things being equal...

MBP comprised more than 50% of the granule protein and localized in the core of the eosinophil secondary granules. MBP-1 damages cells by disrupting the lipid bilayer membrane or altering the activity of enzymes within tissues [25]. MBP-1 stimulates mediator (histamine) release from basophils an...
197 By exploiting the immunomodulatory properties of microorganisms and implementing colonization resistance strategies, it is hoped that dependence on antimicrobial drugs will be reduced and a promising path will be opened in the present predicament. Regulation and transmission of parental microbiota The ...
Reactive oxygen species (ROS) are bioproducts of cellular metabolism. There is a range of molecules with oxidizing properties known as ROS. Despite those molecules being implied negatively in aging a...
