True or False: Platelets adhere to surface absorbed albumin but not to surface absorbed adhesive proteins.

Platelets play a critical role in hemostasis and wound healing, and their adhesion processes are influenced by various surface molecules. When examining the adherence of platelets to surfaces, it's important to consider the role of adhesive proteins such as fibrinogen, von Willebrand factor, and others that facilitate this process.

Platelets can adhere to surfaces coated with adhesive proteins because these proteins contain specific binding sites that interact with receptors on the platelets. For example, fibrinogen binds to the platelet glycoprotein IIb/IIIa receptor, enabling effective adhesion and aggregation at sites of vascular injury. On the other hand, while albumin can also coat surfaces, it does not possess the specific binding properties that facilitate platelet adhesion in the same way that adhesive proteins do.

Therefore, the statement is false because platelets do adhere to surfaces absorbed with adhesive proteins, as these proteins are essential for their activation and aggregation in response to vascular injury. This distinction is key for understanding the mechanisms of platelet activation and the implications for thrombus formation in various conditions.
