**Core Concept**
Snake venom contains a complex mixture of bioactive molecules, including enzymes, peptides, and proteins, designed to immobilize or kill prey. The enzymes present in snake venom play a crucial role in the venom's toxic effects, such as coagulopathy, hemolysis, and neurotoxicity.

**Why the Correct Answer is Right**
The correct answer is **Phospholipase A2 (PLA2)**, an enzyme that hydrolyzes phospholipids to release arachidonic acid, leading to the production of prostaglandins, leukotrienes, and thromboxanes. This results in inflammation, pain, and edema. PLA2 is a major component of many venomous snake species, including cobra, viper, and rattlesnake venoms. The presence of PLA2 in snake venom is responsible for its coagulopathic effects, leading to hemorrhage and necrosis.

**Why Each Wrong Option is Incorrect**
* **Option A:** Lysophospholipase is not a primary component of snake venom. While it may be present in some snake venoms, its role is not as significant as PLA2 in mediating toxicity.
* **Option B:** Heparinase is not commonly found in snake venom. Although some snake venoms may contain heparinase-like activity, it is not a characteristic feature of most venomous snakes.
* **Option C:** Hyaluronidase is present in some snake venoms, but its primary function is to facilitate the spread of venom through tissues rather than mediating direct toxicity.

**Clinical Pearl / High-Yield Fact**
Remember that snake venom can cause a range of systemic effects, including coagulopathy, renal failure, and cardiovascular collapse. Early recognition and treatment of snake bites are crucial to prevent long-term morbidity and mortality.

**Correct Answer:** C.
