Final answer:
The intestinal epithelium has many CYP3A enzymes. Additionally, villi and microvilli in the intestinal epithelium increase nutrient absorption, with lacteals being an essential component for dietary fat transportation.
Step-by-step explanation:
The intestinal epithelium contains multiple enzymes, including those from the cytochrome P450 (CYP) family, which are important for drug metabolism in the body. The specific CYP enzymes present in the intestinal epithelium include CYP3A, among others. Therefore, the correct answer to the question regarding which CYP enzyme the intestinal epithelium has many of is c) CYP3A.
Additionally, the inner layer of the small intestine is characterized by structures such as villi and microvilli, which greatly increase the absorption of nutrients. These structures are most associated with b) lacteals, which are small lymphatic vessels within the villi that absorb dietary fats and transport them to the circulatory system.
