### Questions

- What was the purpose of this assignment?
- The purpose of this assignment was for us to think about what we want to do for our research project. We narrowed down a topic and identified two outside sources.

- Which project is easiest? Why?
- The third option might be the easiest because it's only factoring one other variable, the ammonia feed.

- Which project is hardest? Why?
- I think 4 is the hardest because it asks to develop a model of a ammonia sensor. This requires us to think about 2 nitrogen sensors, which I think might be difficult to think of.

- How might you tweak/revise/recreate the matlab codes we've developed to analyze your model?
- We will probably have to introduce new variables and set of equations if we want to factor in another component of the system.

## Kevin McKay week 6 Journal

- The purpose of this assignment was to use the skills we have been practicing over the last few weeks in modeling and analyzing bioogical systems.
- Personally I find none of them to be easy, I am not great at math modeling.
- Number 4 Seems to be the hardest one because that is the one I would find hardest to begin.
- I am going to have to tweak the differential equations so I get more accurate graph results.

### Questions

- What was the purpose of this assignment?
- This assignment allowed us to begin to think about our project topic. It also gave us the opportunity to find sources other than the original terSchure papers so we have more information to be able to completely understand our topic.

- Which project is easiest? Why?
- I think they all seem to have a challenging, however, I think project three is the easiest. It only requires looking at the ammonia feed, and just altering the current models we have from per cell to per chemostat.

- Which project is hardest? Why?
- I think project two might be the hardest. From what we discussed in class, it would require having an in depth knowledge of anaerobic and aerobic reactions in yeast, as well as how to model the reactions based on the amount of glucose.

- How might you tweak/revise/recreate the matlab codes we've developed to analyze your model?
- We will have to determine the constant to keep the ammonia feed rate at, and then run tests at different dilution rates to see what happens to the model. We can look at the changes made too if the rate coming in is different than the rate coming out.
