Which of the following are examples of exocytosis?

Exocytosis is basically when your vesicles transport materials out of a cell.

Once the neurotransmitters are synthesised and packaged into vesicles, they are transported until the vesicles reach the cell membrane. Then the 2 bilayers rearrange themselves so that the vesicles are able to fuse with the membrane . Once that occurs, the neurotransmitters will spill out whatever it was carrying.

Two examples of exocytosis are

1) your nerve cells releasing transmitters (explained in the description above)

2)your T cells sending vesicles filled with enzymes to viral infected cells

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
