sex cycle

When you reach all the different bases with a different partner in one night. ie. you make out with someone, you get fingered or a hand-job from someone else, oral sex with yet another partner and finish the night going all the way!

Hey man, so I went to Bennigan's last night and totally pulled off the "sex cycle"...
Dude...Teach me!

In swimming, a cycle is 75 yards consisting of 25 yards of backstroke, breaststroke, and freestyle, in that order respectively. It is essentially a 100 IM without the fly.

Today's swimming warm-up will be four cycles.

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!
