Nаturаl Prоducts (Cаnvas Q12, Handwritten Pages Q12ab) Backgrоund: Alkalоids are a type of compound produced by many organisms (known as a natural product). Many of these compounds are biologically active: some alkaloids can be used as stimulants, while others are highly toxic to living organisms. Question: While studying a newly discovered plant, a biochemist has managed to isolate a new alkaloid that shows promise as an antiviral drug. To characterize this new compound, the biologist wants to determine the molecular formula of this substance. Elemental analysis indicates that this compound contains only carbon (59.2%), hydrogen (6.2%), and nitrogen (34.5%). An accurate molar mass could not be measured, but the compound is estimated to have a molar mass close to 150 g/mol. What is the empirical formula of this compound? [emp] What is the molecular formula of this compound? [molec] (Enter your formula with C and H first, followed by the other elements in alphabetical order. The blanks will not allow you to enter subscripts; type them in as normal numbers. For example, water would be entered as just "H2O". You should still be using proper subscripts on your work, though!) (Additional 10 points) On your Handwritten Pages, show all of your work for finding the empirical formula ( Q12a ) and the molecular formula ( Q12b ). Box your final answers. 

Pоwerhоuse оf the Cell (Cаnvаs Q13~15, Hаndwritten Pages Q13) Background: Mitochondria are the component in our cells that break down sugar to produce energy that is used to power the cell, and do things such as move around and divide, among many other functions. One of the first steps in the breakdown of sugar in the mitochondria requires a special enzyme known as citrate synthase; this enzyme is essentially one very large molecule that makes the desired reaction run more efficiently. Question: A research lab is interested in studying the details of how citrate synthase works, and makes their own modified version of the enzyme. Experiments indicate that this citrate synthase variant has a mass of 1.[mass] × 10−19 g per molecule. What is the molar mass of the modified citrate synthase? (Additional 4 points) On your Handwritten Pages, show all of your work and box your final answer. ( Q13 ) Type in only the numerical portion of your answer, properly rounded to the correct number of sig figs, here. (Note: Canvas will automatically insert comma separators if your value is greater than 1000. Your work, however, should NOT include comma separators!)
