It is necessary to phosphorylate a glucose molecule so as to trap glucose inside the cell, to make ATP, and to facilitate enzyme building. When insulin is released from the pancreas after a meal, it signals the tissues to uptake glucose. When glucose enters the cells via glucose transporters, there is a chance for them to leave the cell. If the body is in need of energy, and the breakdown of glucose will provide that energy, the body does not want the glucose to leave the cell and that is why the glucose is phosphorylated by ATP to become glucose-6-phosphate, which now bears a charge.
<span>When you are pregnant, you do not ovulate because you have already fertilized an egg and it is embedded into the uterus where it is growing into a baby. The body knows this, so it does not shed the uterine lining. The shedding of this lining is triggered by hormones which change when the body is pregnant. During pregnancy, a large amount of progesterone is initially produced which helps to prevent the lining from shedding. If you are not pregnant, your progesterone level will begin to decline at the end of your cycle, triggering the shedding of the lining and the period. Birth control pills alter your hormones to mimic a pregnant state. This will prevent the body from releasing an egg and then shedding the uterine lining.</span>
Eutrophication results in the death of trout and other fish as a result of asphyxiation from the lack of oxygen. Eutrophication involves the enrichment of water by nutrients salts such as phosphates, nitrates among others, that causes structural changes of the aquatic ecosystem such as; increased production of algae and aquatic plants, depletion of fish species, deterioration of water quality and other effects that impact negatively the aquatic ecosystem.
