How does the process of opsonization involve the enhancement of phagocytosis by immune cells?
Opsonization is a process where immune cells mark pathogens with molecules called opsonins, making them easier for phagocytes to recognize and engulf. This enhances phagocytosis by promoting the binding of the pathogen to the phagocyte's receptors, leading to its ingestion and destruction.
What else can I help you with?
What is the process called when a cell surrounds a large particle with pseudopodia and then engulfs it?
Phagocytosis is the process by which a cell engulfs a large particle by extending pseudopodia around it and bringing it into the cell in a membrane-bound vesicle.
What is the structure that is not part of the process of the phagocytosis in a ciliate?
Nuclei is not part of the process of phagocytosis in a ciliate. Phagocytosis involves the ingestion of particles or other cells by the cell membrane and their digestion in the cytoplasm, but the nuclei are not directly involved in this process.
What is the function of the complement cascade called opsonization?
Opsonization is a process in which pathogens are marked for destruction by phagocytic cells. It involves the binding of complement proteins to the surface of the pathogen, making it easier for phagocytes to recognize and engulf the pathogen.
Compare phagocytosis and pinocytosis?
Phagocytosis and pinocytosis are both types of endocytosis, which occurs when a substance is brought into the cell. Phagocytosis is called cell eating, while pinocytosis is referred to as cell drinking.
What is the name of the process where a white blood cell engulfs a pathogen?
Phagocytosis is the process by which a white blood cell engulfs and destroys pathogens such as bacteria or viruses. In this process, the white blood cell surrounds the pathogen with its cell membrane, forming a vesicle called a phagosome, which then fuses with lysosomes to break down the pathogen.
How does opsonization occur?
Opsonization occurs when antibodies or complement proteins bind to pathogens, such as bacteria, making them more recognizable to phagocytic cells like macrophages and neutrophils. This facilitates the process of phagocytosis, where the pathogen is engulfed and destroyed by the immune cells.

What is the process by which extensions of cytoplasm engulf large particles called?
Endocytosis:==> Phagocytosis or Pinocytosis. Endocytosis is the name given to the process of cells absorbing molecules. Pinocytosis is intended for small molecules Phagocytosis is for large particles. (larger then ~around 0.75 µm in diameter)

Opsonization is a process in which pathogens are marked for destruction by phagocytic cells. It involves the binding of complement proteins to the surface of the pathogen, making it easier for phagocytes to recognize and engulf the pathogen.
Capsules interfere with a process in neutrophils called what?
Phagocytosis
By what process do leukocytes absorb entire bacteria?
Phagocytosis

Process often thought of as cell eating is?
Phagocytosis is the process often thought of as cell eating. In phagocytosis, a cell engulfs and digests particles, such as bacteria or other microorganisms, by forming a membrane-bound vesicle called a phagosome. This process is mainly carried out by specialized cells of the immune system, such as macrophages and neutrophils.
What process is responsible for bringing in large particles into the cell?
Phagocytosis is the process responsible for bringing in large particles such as bacteria or dead cells into the cell. During phagocytosis, the cell engulfs the particle by forming a phagosome, which then fuses with lysosomes to break down the ingested material.
What do primary active transport phagocytosis exocytosis and endocytosis all have in common?
They all involve the transport of molecules across a cell membrane. Primary active transport requires energy input from ATP to move molecules against their concentration gradient. Phagocytosis is the process by which cells engulf solid particles. Exocytosis and endocytosis involve the movement of molecules in and out of the cell using vesicles.
