Final answer:
When you get a bleeding wound, your body responds by clotting the blood to stop the bleeding. The protein thrombin is created in the ribosomes and then transported to the site of injury to help in the formation of a blood clot.
Step-by-step explanation:
When you fall and get a bleeding wound, your body responds by clotting the blood to stop the bleeding. The process of blood clotting involves the creation of the protein thrombin, which helps in the formation of a blood clot. This protein is made in the cell organelles called ribosomes, which receive instructions from the nucleus to produce the protein. The protein is then transported to the location of the injury through a process called exocytosis, where it is released from the cell through the cell membrane. The Golgi apparatus and endoplasmic reticulum also play roles in the packaging and transport of proteins within the cell.
