Fun Fact #1

Today our biochemistry lectures covered our cells' usage and storage of sugar, which includes what I remember fearing in BYU's biochemistry course: THE KREBS CYCLE.

I just remembered going over every step and every enzyme in such detail that it felt incredibly difficult to learn! The picture above illustrates how I felt about it, like a complicated spiral of doom. Med school has a different approach to things like this. As there is so little time to cover everything, where at BYU we spent about 1 week on the above illustration, today we spent about 15-20 minutes on it. In fact, the illustration below depicts the level of detail with which covered it:

We had so little time that they basically had to say, "Krebs Cycle? It's just a wheel that spins round and round! Don't you forget it!" I hope that illustrates about how fast we have to cover some materials in school, thank goodness for remembering some things from BYU. Most importantly, today's lecture material covered:

FUN FACT #1

We were all taught in school that you breathe in oxygen, then use it in cellular respiration to create energy and carbon dioxide, which you breathe out. Just like all things you learn, there is deeper truth: The oxygen you breathe in is used in cellular respiration, but it becomes water. The food you eat and "burn" as fuel is broken down to carbon dioxide which you breathe out! So you pee out the air you breathe and breathe out the food you eat.
