The uptake of material through the plasma membrane by the formation of a vesicle is endocytosis, whereas the fusion of a vesicle with the plasma membrane and the release of its contents outside of the cell is called exocytosis.
Endocytosis and exocytosis are two active transport processes through which cells move macromolecules across the cell membrane.
<em>While the former involves the capturing of materials from the surrounding of the cell and engulfing such through the cell membrane by forming a phagocytic or pinocytic vesicle, the latter involves the fusion of vesicles to the plasma membrane and the release of the contents of the vesicles to the outside of the cell.</em>
The uptake of material through the plasma membrane by the formation of a vesicle is <u>endocytosis</u>, whereas the fusion of a vesicle with the plasma membrane and the release of its contents outside of the cell is called <u>exocytosis</u>.
Explanation:
Endocytosis is a generalized term for whenever a cell takes in large molecules and other particulate matter available outside the cell, it does so b phagoctosis, pinocytosis and receptor-mediated endocytosis. The material is uptaken through the plasma membrane by the formation of a vesicle.
Exocytosis is a process b which large amounts of material, or large undissolved particles , are moved from cell's cytoplasm to the outside environment by the fusion of a vesicle with the plasma membrane and the release of its contents outside of the cell.
The FSH will decrease and remain at a low level during the 15-28 days of the cycle because at this stage, the egg is waiting to be fertilized. The FSH needs to be low to prepare the uterus lining in case the egg will be fertilized.
