Figure 1-1: A flow chart of the two types of cofactors. Apoenzyme-An enzyme that requires a cofactor but does not have one bound. An apoenzyme is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor. Holoenzyme-An apoenzyme together with its cofactor. A holoenzyme is complete and catalytically active. Most cofactors are not covalently bound but instead are tightly bound. However, organic prosthetic groups such as an iron ion or a vitamin can be covalently bound.
Chyme (/kaÉªm/ ; from Greek ÏÏÎ¼ÏÏ khymos, juice) is the semifluid mass of partly digested food that is expelled by the stomach into the duodenum and moves through the intestines during digestion.ith a pH of approximately 2, chyme emerging from the stomach is very acidic. The duodenum secretes a hormone, cholecystokinin (CCK), which causes the gall bladder to contract, releasing alkaline bile into the duodenum. CCK also causes the release of digestive enzymes from the pancreas.
