As you can see on the Lycoming chart above the EGT provides us a way of finding those mixtures. Best Economy Mixture The Best Economy range begins at peak EGT, and continues on the lean side until the engine won't run smoothly anymore (usually the limit is about 100-150 degrees Lean of Peak). Operating the engine at Best Economy mixture provides the most power for the least amount of fuel, and thus the longest endurance.
Common uses in Biological Systems [edit]. Digestive enzymes are activated in the stomach and pancreas using this methodology. They are synthesized first as zymogens. Pepsinogen is the inactive protein which is initially transcribed.Then, it is cleaved in the stomach to produce Pepsin, a digestion enzyme.The purpose of this regulation is to prevent the Pepsin from digesting proteins in the body before it is introduced into the digestive tract.ommon uses in Biological Systems [edit].

Pepsinogen is a proenzyme(enzyme which is in inactive form). It is released from gastric glands of stomach in particular Peptic cells/chief cells. Pepsinogen is converted into an active enzyme ,pepsin by the action of HCl in stomach.HCl helps to provide acidic medium which is essential for the activation of pepsinogen. Activated pepsin itself activates more and more pepsinogen (autocatalysis)
