When platelets stick to each other and to the blood
vessel they form a plug in the hole of the vessel. This process is called platelet aggregation.
Before the plug forms, a platelet will stick to the blood vessel (adhesion), change its shape
and signal other platelets to come help (activation and secretion). Then they
stick to each other (aggregation).
Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol. Both fermentation pathways also oxidize NADH to NAD+ during the process.
