Krebs Cycle

The process in which 2 pyruvic acid molecules from glycolosis is converted into 8 NADH, 2 ATP, and 2 FADH2. Each yields NADH yields three ATP through the electron transport chain and each FADH2 yields 2 ATP. Oxygen is required to create a proton gradient so NADH and FADH2 so it could be converted into ATP by ATP Synthase, an enzyme. Since this requires Oxygen, this is a form of aerobic respiration. ATP synthase is located on the mitochondria membrane of eukaryotes and on the plasma membrane of prokaryotes.

I hate everyone who does not know what the Krebs Cycle is!

menstrual cycle

The span of 28 days, any of which, 5-7 could be the worst of a mans life. During these days, woman cramp, ache, and bitch. The combination of these makes for one fussy little lady which in many cases may lead to a breakup if an excessive ammount of time is spent with the periodee.

"Wow, Katie looks good today"
"U'r my fucking boyfriend Johnny!!! You like her more than me, I thought I meant something to you... You want her you can have her. You always talk about her I bet. Never talk about me to her I bet. Or to any of your friends. I bet you dont even think about me. *starts crying* I'm so sorry, i love you, never leave me. I'm sorry. I'm sorry. *Starts crying again*"
"Wow, I wish I had a menstrual cycle just like you!"

Skurman Cycle

The reboot cycle on a public vending machine that clears stucks products. Can be forced by unplugging the machine.

Yeah, my diet coke got stuck in the machine so I pulled the power plug and forced it into a Skurman cycle. It spat that can right out.

Full Cycle

Noun: A full rotation of piss, shit, and cum (not necessarily in that order). A full cycle is typically had in the toilet but may also take place in one's pants.

Give me a sec, I'm about to have a full cycle in the bathroom.
