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.
SHIP: Container ships carry cargo in containers, the kind you see on freight trains, and are responsible for moving around much of the world's manufactured products. Our ship, the MV Hanjin Madrid, is Korean-owned, and managed by NSB, a German shipping company.RY THIS AT HOME, KIDS: Taking a container ship instead of a plane worked out really well for us. Container ships are neither sustainable nor scalable, but to the extent that it's greener than flying, we'd totally encourage folks to give freighter travel a try.
