The key factor that controls the initial rate of an enzyme catalysed reaction (Vo) is the concentration of the substrate of the reaction ([S]). In Damon's Michaelis-Menten experiment, the highest concentration of substrate used was 500 UM. What do you think will happen to the reaction velocity if higher concentrations of substrate were used? Select one: a. Vo will reach a plateau at higher (S) values O b. Vo will increase exponentially as (S) is increased O c. Vo will...

Any help would be appreciated!
N-tosyl L-AA-chloromethylketones (see structure to the right) have proven to be effective irreversible inhibitors of members of the family of serine proteases. Given what you have learned about the substrate specificity pocket in this class of enzymes, which of the compounds listed below would you expect to be the most effective inhibitor for elastase? CIRCLE the most correct answer. R = Met side chain R = Leu side chain R = Ala side chain R...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
