Indicate which statements are true. Correct all false statements by changing the underlined words.


__________ Opsonization occurs when a phagocyte’s pseudopods surround a microbe and fuse to form a sac.

Verified step by step guidance

1. Identify the term 'opsonization' and understand its definition in microbiology.
2. Recognize that opsonization is a process that enhances phagocytosis by marking pathogens for destruction.
3. Understand that opsonization involves the coating of a microbe with opsonins, such as antibodies or complement proteins, to facilitate recognition by phagocytes.
4. Clarify that the statement describes phagocytosis, not opsonization. Phagocytosis is the process where a phagocyte's pseudopods surround a microbe and fuse to form a phagosome.
5. Correct the statement: 'Phagocytosis occurs when a phagocyte’s pseudopods surround a microbe and fuse to form a sac.'

Key Concepts

Opsonization

Opsonization is a process that enhances the ability of phagocytes to recognize and engulf pathogens. It involves the binding of opsonins, such as antibodies or complement proteins, to the surface of microbes, marking them for destruction. This process increases the efficiency of phagocytosis, allowing immune cells to more effectively eliminate invaders.

Phagocytosis

Phagocytosis is a cellular process where certain immune cells, known as phagocytes, engulf and digest pathogens or debris. During this process, the phagocyte extends its membrane to surround the target, forming a vesicle called a phagosome. This vesicle then fuses with lysosomes to degrade the engulfed material, playing a crucial role in the immune response.

Pseudopods

Pseudopods are temporary, foot-like extensions of a cell's cytoplasm that are used by some cells, including phagocytes, to move and engulf particles. These structures are formed by the rearrangement of the cytoskeleton and allow the cell to change shape, facilitating the process of phagocytosis by surrounding and enclosing pathogens.
