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: A B C
Explanation:
The synthesis of ATPS takes place in the mitochondrial and chloro plasts of cells.It is an exergonic reaction that involves the use of energy released from influx of protons to for the catalysis of in organic phosphate and ADP by enzyme ATP Synthase in the stroma and matrix of chloroplasts and mitochondrial respectively.
The 3 bonds that connected phosphate ions to ADP to form ATP must be broken down(hydrolysis) with water to release the energy for biochemical activities of the cells.
The first bond hydrolysis releases first phosphate and ATP changed to ATP,
The second bond releases breakage changed the ADP to AMP with the release of more energy.
