D)phagocytosis.
E)hemolysis.

Question

Quizplus · Accepted Answer

Chemotaxis refers to the movement of leukocytes (white blood cells) in response to certain chemicals, such as cytokines or chemokines, that are produced at the site of infection or inflammation. This process helps the leukocytes to locate and eliminate the pathogens or damaged cells that are causing the problem. Opsonization refers to the coating of pathogens or foreign particles with antibodies or complement proteins, which makes them more recognizable and easier to phagocytize by leukocytes. Chemoreception refers to the ability of cells to detect and respond to chemical signals in their environment, but it is not specific to leukocyte movement. Phagocytosis refers to the process of engulfing and digesting foreign substances by leukocytes, while hemolysis refers specifically to the destruction of red blood cells.
