Okay, don't yawn: The Krebs Cycle refers to a series of chemical reactions involved in aerobic respiration that occurs naturally in animals, otherwise known as the citric acid cycle. Unfortunately, no matter how you look at it, this cycle contains a lot of steps.
But there is one thing that might help — if you can handle it. Desperate times call for desperate measures, right? Before you go any further, plug some headphones into your computer or wait until you're alone (trust me), and then check out the link below for "The Krebs Cycle" song. Yes, you heard that correctly. Someone — namely Lynda Jones of the band Science Groove — has come to your rescue by putting the basics of the Kreb Cycle to music.
Now the trick is to put your good taste in music aside and listen to this over and over... and over again. Just be careful not to hum too loudly during your final exam.
