Question

There are three types of endocytosis; which option correctly identifies all three types and is correctly matched?

A) Phagocytosis – cell engulfs large particles; Pinocytosis – cell takes in small particles; Receptor-mediated endocytosis – specific molecules are taken in after binding to receptors.
B) Pinocytosis – cell engulfs large particles; Phagocytosis – cell takes in small particles; Receptor-mediated endocytosis – non-specific molecules are taken in.
C) Receptor-mediated endocytosis – cell engulfs large particles; Phagocytosis – cell takes in small particles; Pinocytosis – specific molecules are taken in after binding to receptors.
D) Phagocytosis – non-specific molecules are taken in; Receptor-mediated endocytosis – specific molecules are taken in after binding to receptors; Pinocytosis – cell engulfs large particles.

Answer 1

Option A correctly identifies the three types of endocytosis: phagocytosis (cell engulfs large particles), pinocytosis (cell takes in small particles), and receptor-mediated endocytosis (cell takes in specific molecules after binding to receptors).

Step-by-step explanation:

The correct identification and match for the three types of endocytosis are as follows: phagocytosis is a process where the cell engulfs large particles and is relatively non-selective. Pinocytosis involves the cell taking in small particles in fluid, which is also non-specific. Lastly, receptor-mediated endocytosis is highly selective, taking up specific molecules after they bind to receptors on the cell surface. Given these explanations, the correct option that identifies all three types of endocytosis is: A) Phagocytosis – cell engulfs large particles; Pinocytosis – cell takes in small particles; Receptor-mediated endocytosis – specific molecules are taken in after binding to receptors.
