Embalming 1: Exam 4 Material Flashcards
____ (2 types) of decomposition of any type of protein, and can occur in the presence or absence of oxygen
Proteolysis
The separation of compounds into simpler substances by the action of microbial and/or autolytic enzymes is the definition of ____.
Decomposition
____ is decomposition of proteins by the action of enzymes from anaerobic (absence of free oxygen) bacteria; was named of the horrific smelling odors. This form of proteolysis advances much quicker than the form of proteolysis that occurs in the presence of oxygen.
Putrefaction
Decomposition of proteins by enzymes of aerobic (the presence of free oxygen) bacteria is ____.
Decay
____ is the decomposition of fats (one substances formed as a result of lipolysis is adipocere (grave wax)
adipocere begins within days of death and becomes visible in about 3 months
Lypolysis
The bacterial decomposition of carbohydrates is ____.
Fermentation
____ is the decomposition of ANY sugar
Saccharolysis
____ is a reaction in which water is one of the reactants and compounds are ofter broken down; the key method of which decomposition occurs. The splitting or tearing apart of compounds by the addition of water, this is how proteins, sugars, and fats break down.
Hydrolysis
____ is self destruction of cells by enzymes of their own formation; decomposition of all tissues by enzymes of their own formation without microbial assistance.
a. role of lysosomes (cell organelee that contains digestive enzymes) in autolysis
b. when the pH of the tissue becomes acidic it causes the lysosomes to rupture
c. in the presence of water, the released enzymes begin to digest carbohydrates, proteins, and fats
Autolysis
Signs of Decomposition are?
- Color Change: first external sign of decomposition is over the lower right quadrant of the abdomen
- Odor: penetrating & nauseating
- Purge: the post mortem evacuation of any substance from an external body orifacea as a result of pressure
