Question

What are the similarities and differences between endocytosis and exocytosis?

Answer 1

Similarities include:
Both are involved in transporting big molecules across the membrane.
Both do so using a vesicle.
Both need energy.
Differences are:
Endocytosis brings materials to the inside of the cell while exo takes them out.
Exoocytosis has the vesicle being formed in the golgi apparatus which then fuses with the membrane, while endo has the vesicle. formed from the cell membrane which then gets into the cytoplasm.
Exocytosis increases the size of the cell membrane while endo does the opposite.
