Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Exocytosis is the movement of
A
any type of substance from outside the cell to the inside of the cell.
B
very large substances from outside the cell to the inside of the cell.
C
any type of substance from inside the cell to the outside.
D
very large substances from inside the cell to the outside.
Explanation: 

Detailed explanation-1: -Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell, as s hown in Figure below. Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.

Detailed explanation-2: -What is exocytosis? Exocytosis definition and purposes. Exocytosis is the process by which cells move materials from within the cell into the extracellular fluid. Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Detailed explanation-3: -Endocytosis and exocytosis are the mechanisms by which cells transport items that are too big to pass through the lipid bilayer of the cell membrane directly into or out of the cell. Exocytosis and endocytosis are two processes that allow large molecules, bacteria, and waste materials to pass through the cell membrane.

Detailed explanation-4: -Exocytosis (/ˌɛksoʊsaɪˈtoʊsɪs/) is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell (exo-+ cytosis).

Detailed explanation-5: -Exocytosis is a process for moving large molecules out of the cell to the cell exterior.
