Which organ is primarily involved in enzymatic drug degradation?

Explanation:
The main idea is that drug metabolism is dominated by the liver because it contains a high concentration of enzymes that chemically modify drugs. The liver houses the cytochrome P450 system and many other conjugating enzymes (like UGTs and SULTs) that transform lipophilic drugs into more polar, water-soluble metabolites. This makes them easier to excrete and is the reason why oral drugs often undergo a first-pass effect, reducing the amount that reaches systemic circulation. While other organs can contribute to metabolism to some extent, the liver is the primary site for enzymatic drug degradation, making it the best answer.
