aksik [14]

According to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.

What is exocytosis?

It is the expulsion, by cells, of particles that, due to their size, cannot pass through the cell membrane.

In this sense, it is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted. Insulin is released to the outside by exocytosis, intervening in the process of glucose entry into cells.

Therefore, we can conclude that according to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.
