Platelet activation involves the release of granules containing which substances that further amplify aggregation?
Show answer and explanation
Correct answer: ADP and Serotonin (5-HT)
Upon activation, platelets undergo degranulation, releasing ADP from dense granules and various proteins from alpha-granules. ADP then binds to P2Y1 and P2Y12 receptors on nearby platelets to recruit them into the growing clot.
