Which of the following is a function of eicosanoids?

• A. Energy storage
• B. Cell recognition
• C. Intercellular communication
• D. Structural support

Answer: (C)

Eicosanoids play a crucial role in intercellular communication, which is why the correct answer is intercellular communication. They are signaling molecules derived from fatty acids, particularly arachidonic acid, and are involved in various physiological processes. Eicosanoids include prostaglandins, thromboxanes, and leukotrienes, all of which facilitate communication between cells, influencing inflammation, immune responses, and the regulation of blood flow.

These molecules act locally by binding to specific receptors on target cells, leading to a cascade of biochemical events that result in cellular responses. This ability to mediate communication is essential for maintaining homeostasis and coordinating complex physiological processes within the body. In contrast, energy storage, cell recognition, and structural support are not primary functions of eicosanoids, as these roles are typically associated with other biomolecules like carbohydrates, proteins, and lipids.
