Over [174]

Answer:

Sickle cell disease in an autosomal recessive inherited disease which is caused by the mutation in the HBB (hemoglobin-β gene) gene present on the chromosome no. 11. In sickle cell, the red blood cells become sickle shape due to the abnormal shape of hemoglobin present in it.

These sickle cells are known to form a blockage in the blood vessels thereby causing damage to the vital organs. Human spleen constantly destroys sickle cells because they get trapped in it which causes a disease called sickle cell anemia.

Sickle cell anemia is normally the problem in genetic disease which is inherited from the parents to children. When both the DNA strand has a mutation in their HBB gene then only this disease will affect the individual.

Much of the regulation of gluconeogenesis is a result of the inhibition of ________. Much of the regulation of gluconeogenesis i
Monica [59]

Answer:

The correct answer will be option- Glycolysis.

Explanation:

Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.

This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.

Thus, option- glycolysis is the correct answer.

ahrayia [7]

Answer:

Tolerance

Explanation:

Tolerance is the capacity of an organism to survive changes in certain environmental and biochemical conditions. It has to with changes an organism is able to withstand when is subjected to certain factors which can biotic or abiotic.

For example, in the consumption of alcohol, tolerance can occur when there is a fast elimination of alcohol from the body system. This is usually as a result of the activation of a group of enzymes that is responsible for the metabolism of alcohol in excessive alcohol drinkers. The activation of this enzymes increases the catabolism of alcohol and hence reduces the active time within the body, hence reducing the time by which alcohol intoxicates.
