WebFeb 5, 2024 · Exocytosis occurs in four steps in constitutive exocytosis and in five steps in regulated exocytosis. These steps include vesicle trafficking, tethering, docking, priming, and fusing. Trafficking: Vesicles are transported to the cell membrane along microtubules of the cytoskeleton. WebApr 28, 2024 · Endocytosis Definition. Endocytosis is the process of actively transporting molecules into the cell by engulfing it with its membrane. Endocytosis and exocytosis are used by all cells to transport molecules that cannot pass through the membrane passively. Exocytosis provides the opposite function and pushes molecules out of the cell.

WebTopic: Cytoskeleton. Flagella and cilia are microtubule-based structures that either help cells to move themselves forward as in the case of flagella or substances along the outer surface of the cell as by cilia. Flagella (singular = flagellum) are long, wavy structures that extend from the plasma membrane and are used to move an entire cell. superman\u0027s mom
