Question

Choose the correct sequence of events that occur in the process of phagocytosis.

• A. Engulfs pathogen in Membrane sac $\to$ Enzymes destroy the Pathogen $\to$ Membrane sac combines with Lysosome $\to$ Remains are expelled
• B. Engulfs pathogen in Membrane sac $\to$ Membrane sac combines with Lysosome $\to$ Enzymes destroy the Pathogen $\to$ Remains are expelled
• C. Membrane sac combines with Lysosome $\to$ Engulfs pathogen in Membrane sac $\to$ Enzymes destroy the Pathogen $\to$ Remains are expelled
• D. Enzymes destroy the Pathogen $\to$ Membrane sac combines with Lysosome $\to$ Engulfs pathogen in Membrane sac $\to$ Remains are expelled

Answer 1

The correct option is B

Engulfs pathogen in Membrane sac $\to$ Membrane sac combines with Lysosome $\to$ Enzymes destroy the Pathogen $\to$ Remains are expelled

Phagocytosis is the process by which phagocytes (monocytes and neutrophils) engulf and destroy the bacteria. The process starts with the cell engulfing the bacteria in what's known as a membrane sac. The membrane sac then combines with lysosome which consists of enzymes. These enzymes destroy the bacteria and then expel the remains.
