Yesterday I had a competition for whomever could guess the physiological cycle the quickest. Broda correctly guessed the citric acid cycle.
The citric acid cycle, or more commonly known as the Krebs cycle (after Hans Krebs) is the process is which the cells' mitochondria make energy in the form of ATP (adenosine triphosphate). It is the most common cycle in which your body produces energy, as it is the most efficient. The process involves glucose that has been broken down into Acetyl-CoA going through a number of chemical reactions that finally net an end result of about 30 molecules of ATP per each molecule of glucose. Far more efficient than the two molecules of ATP per glucose molecule that anaerobic glycolysis produces.
So why do we have different cycles for producing energy if one is far more efficient, you ask? Well let me tell you my little sasquatches; it's because the Krebs cycle must have oxygen to function. This makes it an aerobic energy production method. Anaerobic glycolysis is as it's name implies, it uses no oxygen. This is the cycle you use when you're exercising heavily and not enough oxygen is getting to your muscles. This process also produces lactic acid, which is why your muscles burn after such exercises.
Well, enough of that, we must get to the prize. As promised a personalized drawing by me, to you for your profound knowledge in the field of basic physiology.
What? The man's a programmer, I'm sure he'll like it.
In other news, I had uni today, and we were in the nursing labs. I have no idea why (especially because this is the first time I've met this teacher), but we had to practice palpating (feeling) a patients chest, stomach et cetera, and she just looked at me and said "you're the patient". So I had to remove my shirt and lay on a bed while students poked and prodded my bare body. It was definitely an experience I won't forget, especially because I'm not what you'd call slender.
Anywho, just another experience under the belt.
