SIZIF [17.4K]

Answer:

Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?

Eva8 [605]

Answer:

The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.

Explanation:

In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.

Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.

In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).

Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.
