Major bacterial enzyme responsible for putrefaction
**Core Concept**
Putrefaction is a process of microbial decomposition of organic matter, primarily occurring in the absence of oxygen. It is a result of the action of various enzymes produced by bacteria, leading to the breakdown of proteins, fats, and other cellular components.
**Why the Correct Answer is Right**
The major bacterial enzyme responsible for putrefaction is **proteolytic enzyme**, specifically leucine aminopeptidase. This enzyme breaks down proteins into peptides and amino acids, which are further metabolized by other microorganisms. The action of leucine aminopeptidase is crucial in the decomposition process, allowing bacteria to utilize the protein-rich environment for growth and multiplication.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while **lipase** is an enzyme involved in the breakdown of fats, it is not the primary enzyme responsible for putrefaction.
**Option B:** This option is incorrect because **lactase** is an enzyme involved in the breakdown of lactose, a sugar found in milk, and is not directly related to putrefaction.
**Option C:** This option is incorrect because **amylase** is an enzyme involved in the breakdown of carbohydrates, specifically starches and glycogen, and is not the primary enzyme responsible for putrefaction.
**Clinical Pearl / High-Yield Fact**
The process of putrefaction is influenced by factors such as oxygen levels, pH, and the presence of microorganisms. The breakdown of proteins by leucine aminopeptidase can lead to the release of toxic compounds, including ammonia and amines, which can have significant clinical implications in cases of tissue damage or infection.
**Correct Answer: D. Leucine aminopeptidase**
