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.
The best answer I see is A
please tell me if I´m right
sorry if i am not
ATP stores and transports energy in the cells, usually in the mitochondria. Energy is released by hydrolysis (carbohydrates being broken down into sugar molecules), which eventually results in forming ADP (adenosine diphosphate) that absorbs the energy and recharges the phosphate group and ATP
My best explanation is
Some cancer is in blood and tissue and doesn’t form a tumor, such as leukemia. Therefore a usage of “chemotherapy” is needed.
Sorry if this isn’t a good explanation
It is for the cells to make protein.
