Endocytosis moves materials _____ a cell via _____.
A: Out of … diffusion
B: Out of … membranous vesicles
C: Into … membranous vesicles
D: Into … a transport protein
E: Into … facilitated diffusion
The correct answer is option C.
Endocytosis moves materials into a cell via membranous vesicles.
Through a cell membrane, the substances enter into the cell by different methods. It depends on the type of substance and the size of the particles. Those particles which are large in size move into the cell by endocytosis.
Endocytosis is a process in which a massive particle is taken into the cell, which is surrounded by cell membranes. Then it pinches inward so that to form a vesicle that contains the particle. The intake of fluids into the cell through this way is called pinocytosis.
Phagocytosis is the intake of large solid particles into the cell. Most members of the Protista use phagocytosis and pinocytosis to engulf the liquid and solid particles.
There are different types of endocytosis;
- clathrin-mediated endocytosis and
- caveolae-mediated endocytosis.
The clathrin-mediated mechanism is somehow complicated and involves various proteins. However, the caveolae-mediated process is different and involves little cave-like invaginations being formed in the membrane during the process.
