Which of the following are examples of exocytosis?
Alexxx [7]

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

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all thr
Sati [7]

The cell reaches equilibrium in a hypertonic solution by removing water from it so that the two concentrations are isotonic, in a hypotonic solution the water will move into the cell and in an isotonic solution the water will not move anywhere anymore. Both cells have the same solute concentration.

<h3>How do these equilibrium processes occur?</h3>

The hypertonic solution is the one that has a solute concentration greater than that of the cell, so in order to reach the same concentration, the water in the cell will leave to equal the solute concentration in the cell. The hypotonic solution, on the other hand, is the one that has a lower solute concentration than the cell, so the water will enter the cell to have the same concentration.

Finally in the isotonic solution nothing will happen, since both inside the cell and in the solution itself there will be the same concentration of solute, so no concentration has to be equalized.

Therefore, we can confirm that the cell reaches equilibrium in a hypertonic solution by removing water from it so that the two concentrations are isotonic, in a hypotonic solution the water will move into the cell and in an isotonic solution the water will not move anywhere anymore. Both cells have the same solute concentration.
