Pepsinogen I is secreted by chief cells, and pepsinogen II is secreted by pyloric glands. The secretion of pepsinogen is stimulated by vagal stimulation, gastrin, and histamine. Pepsinogen I is mainly found in the body of the stomach, where most acid is secreted. Pepsin is a proteolytic enzyme, whereas pepsinogen is a proenzyme. â¢ Pepsin is the active form of pepsinogen while pepsinogen is the inactive precursor of pepsin. â¢ Unlike the pepsin, pepsinogen is secreted by chief cells and pyloric glands.
A reefer ship is a refrigerated cargo ship; a type of ship typically used to transport perishable commodities which require temperature-controlled transportation, such as fruit, meat, fish, vegetables, dairy products and other foods.
Reefer trailers use 1/4 tank of fuel every 24 hours on continuous run. But understand a Reefer Trailer has nothing to do with your MPG whatsoever. Reefers fuel is based on time not miles. The average truck reefer or not, should get between 6 and 7 mpg.Fully weighted (around 45,000), you should get at least 5.0 mpg in the Rocky Mountains-probably the worst terrain for fuel mileage.f course the temperature of the load will effect the run time of the reefer, and in turn the mpg, but a fully loaded tractor should get 6-7 mpg and a reefer unit will consume about 1 gallon per hour. As a quick number, the combo will run about 6-6.5mpg.
