Vesicle-Based Transport: Endocytosis and Exocytosis

Practice: One of the functions of antibodies—proteins that are part of the immune system—is to bind to and coat bacteria. This makes the bacteria more likely to be engulfed and destroyed by macrophages. Which of the following processes is likely facilitated by antibodies?

Practice: Below is a microscope slide of pancreatic acinar cells (the darker purple ones). All of those circles within the cell are vesicles packed with proteins to be released. The large number of granules stored by pancreatic acinar cells suggest that they do lots of which of the following processes?
