Question

Which of the following molecule is incorrectly paired with its action ?

• A. Interleukin I-stimulates division of helper T-cells
• B. Interferon-helps neighbouring cells to resist viral infection
• C. Histamine-fights allergic reactions
• D. Lysozyme-attacks bacterial cell walls

Answer 1

Answer: (C)

Histamine-fights allergic reactions

A- IL-1α is produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor.

B- Interferons (IFNs) are a group of signaling proteins made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.

C- When they leave the mast cells, histamines boost blood flow in the area of your body the allergen affected. This causes inflammation, which lets other chemicals from your immune system step in to do repair work.

D- Lysozyme is capable of breaking the chemical bonds in the outer cell wall of the bacteria. Bacterial cell walls contain a layer of peptidoglycan, which is the specific site that lysozyme targets. The peptidoglycan layer contains alternating molecules called N-acetylglucosamine and N-acetylmuramic acid.

So, the correct option is 'Option C'.
