Major bacterial enzyme responsible for putrefaction –
**Core Concept**
Putrefaction is a process of microbial decomposition of organic matter, particularly proteins, resulting in foul-smelling compounds. This process is primarily mediated by bacterial enzymes that break down proteins into smaller peptides and ammonia.
**Why the Correct Answer is Right**
The major bacterial enzyme responsible for putrefaction is **Protease**. Protease enzymes are produced by various bacteria, including Clostridium perfringens, Bacillus subtilis, and Pseudomonas aeruginosa. These enzymes hydrolyze peptide bonds within proteins, leading to the breakdown of proteins into smaller peptides and amino acids, which are then further metabolized to produce ammonia and other foul-smelling compounds.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a bacterial enzyme involved in putrefaction.
**Option B:** This option is incorrect as it refers to a process of cellular respiration, not protein breakdown.
**Option C:** This option is incorrect as it refers to a type of bacterial toxin, not a protein-degrading enzyme.
**Clinical Pearl / High-Yield Fact**
It's essential to note that putrefaction can be accelerated by factors such as oxygen deprivation, high temperatures, and the presence of metal ions, which can activate proteolytic enzymes.
**Correct Answer: C. Protease**
