Textbook Question
Chapter 19, Problem 1R
DRAW IT Label IgE, antigen, and mast cell, and add an antihistamine to the following figure. What type of cell is this? Singulair stops inflammation by blocking leukotriene receptors. Add this action to the figure.
Expert Solution & Answer
Summary Introduction
To determine:
The inflammation of singuliar blocks by blocking leukotriene’s receptors.
Introduction:
Type 1 hypersensitivity can cause immune response to the exposure of antigens. When IgE antibodies bind to the receptors on mast cells, then they will bind to the antigen. It causes degranulation of mast cells and the release of granules like histamine and leukotrienes. It leads to inflammation and breathing difficulties. This is blocked by giving singuliar drug.
Answer to Problem 1R
Correct answer:
A mast cell is given in this figure. An antihistamine is added to the mast cell; it blocks the inflammation.
Explanation of Solution
Diagram:
Leukotrienes attach to the receptors of mast cells; they cause inflammation. When a leukotriene receptor is blocked by singuliar, it stops inflammation. Mast cells play a role in autoimmune disorders. Singuliar (Montelukost) relieve the symptoms of hay fever, asthma, inflammation, and redness in skin. Singuliar mimics as leukotriene receptors.
Conclusion
Anaphylactic hypersensitivity mast cell releases histamine, leukotriene, and other mediators when it binds to the antigen and IgE antibody. When leukotriene receptors are blocked by singuliar, an allergic response does not occur.

Derive processing rates (-k) using a negative exponential model. Include graphs for species 2 through 10 similar or identical to what I have provided for species 1. Re-recreating the graph species 1 with an identical equation will ensure you are doing this correctly. The process is identical to how you derived leaf retention rates.
