Question

epinephrine
what type of lipid signaling molecule controls inflammation and pain response?
beta-carotene
prostaglandins
triglycerides

Explanation:

To determine the lipid signaling molecule controlling inflammation and pain:

• Beta - carotene is a pigment (provitamin A), not a lipid signaling molecule for inflammation/pain.
• Prostaglandins are lipid - derived signaling molecules that regulate inflammation, pain, and other physiological processes.
• Triglycerides are energy - storage lipids, not involved in inflammation/pain signaling.

Answer:

B. prostaglandins
