Answer:
Explanation:
The switch from glutamic acid to valine in position 6 of hemoglobin (HB) forms the basis of sickle cell anemia disease pathology.
Valine is hydrophobic and it's chain is shorter than glutamic acid. The lack of the carboxylic acid and shortness of valine will result in loss of the ionic interactions formed between the glutamic acid's carboxylic group and other amino acids. A hydrophobic cavity will form in the beta sheet of HB due to the short and hydrophobic structure of valine. For these reasons, the HB molecule will be less stable and insoluble in water. The insolubility is thought to be caused by fibril formation between the valine interacting with hydrophobic pocket residues of the adjacent HB molecule. This would in turn affect binding of oxygen to HB.
Answer:
The options
a.) neutrophils
b.) lymphocytes
c.) basophils
d.) monocytes
The CORRECT ANSWER IS a.)
a.) neutrophils
Explanation:
Neutrophils are grouped as granulocytes (they possesses clearly seen cytoplasmic granules). It functions as the body's bacteria killers, and their numbers rises at a swift rate in times of acute bacterial infections. Neutrophils are active phagocytes; they are particularly partial to feed on bacteria. It make up around 40 percent to 60 percent of the white blood cells in the body, and its the first cells produced by the body as a response to a bacterial infection.
