White blood cells use phagocytosis to bring and destroy pathogens. Which of the statements given above is/are correct?

Consider the following statements regarding Cell-Cell interaction: 1. Exocytosis is a process used by the cell to take out its trash and to incorporate proteins into the cell membrane. 2. White blood cells use phagocytosis to bring and destroy pathogens. Which of the statements given above is/are correct? Correct Answer Both 1 and 2

  • Exocytosis is a process used by the cell to take out its trash and to incorporate proteins into the cell membrane. Hence statement 1 is correct.
  • During exocytosis, the phospholipid bilayer of the cell membrane surrounds the waste proteins, creating a bubble-like structure called a vesicle.
  • Vesicles are frequently used in the cell for transportation of molecules across the cell membrane.
  • Exocytosis is also used to integrate new proteins into the cell membrane.
  • There are three different types of endocytosis, Phagocytosis, Pinocytosis and Receptor-mediated endocytosis.
  • Phagocytosis is the process similar to eating, where the cell engulfs a molecule in order to move it to the interior of the cell.
  • White blood cells recognize pathogens, such as viruses or bacterial cells, outside of the cell and will use phagocytosis to bring it in to destroy it. Hence statement 2 is correct.

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: It’s a type of cancer of the blood cells caused by a rise in the number of white blood cells in the body.  Q: There is hardly anything you can do to prevent leukaemia. R: If a person appears pale, swollen gums, an enlarged liver or spleen, significant bruising, bleeding, fever, fatigue, the doctor should suspect leukaemia. S: They crowd out the red blood cells and platelets the body needs to be healthy. All those extra white blood cells don’t work right, and that causes problems.
