Blood Glucose Regulation Lab Essay Sample

1. When was plasma insulin concentration highest? If values are similar for several clip points. so give scope of times when plasma insulin concentration was highest. Plasma insulin concentration was at its highest during the 1 hr station repast clip transcending a concentration of 180. 2. When was plasma insulin concentration lowest? If values are similar for several clip points. so give scope of times when plasma insulin concentration was lowest.

Plasma insulin concentration was at its lowest during the fasting clip period. Concentration was about 68 during that clip. 3. When was plasma glucagon concentration highest? If values are similar for several clip points. so give scope of times when plasma glucagon concentration was highest.

Plasma glucagon concentration was at its highest during the 1 hr station repast clip. at a concentration of 6. 4. When was plasma glucagon concentration lowest? If values are similar for several clip points. so give scope of times when plasma glucagon concentration was lowest.

Plasma glucagon concentration was at its lowest during the fasting clip period. at a concentration between about 1. 6 -1. 8. 5. When was plasma insulin/glucagon concentration highest? If values are similar for several clip points. so give scope of times when plasma insulin/glucagon concentration was highest.

Plasma insulin/glucagon concentration differed significantly. Insulin degrees were at their highest during 1 hr station repast clip transcending 180 while glucagon was it its highest during the 2 hr at 36.

6. When was plasma insulin/glucagon concentration lowest? If values are similar for several clip points. so give scope of times when plasma
insulin/glucagon concentration was lowest.
Plasma insulin/glucagon concentration differed significantly. Insulin degrees were at their lowest during the fasting clip period at about 68 while glucagon was it its lowest during the 1 hr at 35.

Discussion
1. Explain how insulin changed plasma glucose concentration over the class of the experiment. Insulin increases the conveyance of glucose into organic structure cells doing blood glucose degrees to diminish. When the insulin calmed down a spot and decreased that when a rise in glucose was presented.

2. Explain how glucagon changed plasma glucose concentration over the class of the experiment. Glucagon caused blood glucose to increase. Laboratory Report/ Jazmine Ricine Parham/ Blood Glucose Regulation/ Professor Deno/ 12. 03. 2014/ Page [ 3 ] of [ 4 ]

3. Explain what caused the alteration in plasma ketone concentration over the class of the experiment. The break down of fatty acids is what forms ketones so the consumption of the repast that was filled with carbs is what caused the alteration in plasma ketone concentration over the class of the experiment.

4. Explain how negative feedback caused the alterations in plasma insulin concentration observed during the experiment. Well secernment of endocrines are frequently clip referred to as negative feedback. In the cause of insulin you need blood glucose to release it so thats were the negative feedback comes in one needs the other. Carbs led to glucose and glucose secernment leads to insulin production. 5. Explain how negative feedback caused the alterations in plasma glucagon concentration observed during the experiment.

Secretion of endocrines are frequently referred to as negative feedback. In the instance of glucagon high blood glucose stimulates the secernment of insulin by the pancreas and that in bend causes the secernment of glucagon which is where negative feedback comes in ; one needs the other to work. Carbs cause glucose production. glucose leads to insulin. and that insulin secrets glucagon. 6. The insulin/glucagon ratio changed over the class of the experiment indicating alterations in glucose storage and alterations in ability to increase blood glucose concentration via glycogenolysis and gluconeogenesis. State when glucose storage capableness was highest and why.

Glucose storage capableness was at its highest during the 1 hr station repast clip because the carbs that were ingested during the repast caused blood glucose degrees to lift. 7. State when glycogenolysis and gluconeogenesis were highest and why. Glycogenolysis is the transition of animal starch to glucose. low blood glucose stimulates the production and secernment of glucagon so glycogenolysis was at its highest at clip periods where blood glucose were low and that was around the fasting – 0 hr station repast clip. Gluconeogenesis is the transition of glucose from a non carb so Im presuming that this to was at its highest before eating. 8. Explain how a high blood ketone degree helps the organic structure conserve blood glucose. Ketones are transported into cells and so are used to make ATR. The usage of that ATR so creates ATP that conserves blood glucose. thereby assisting to keep normal blood glucose degrees.

9. Repeat your anticipations that were right and give the information from your experiment that supports them. Repeat your anticipations that were non right and rectify them. giving the information from your experiment that supports the rectification. I predicted right that plasma glucose would be higher instantly after the repast. I besides predicted right that plasma glucagon degrees would be highest while fasting. The concentration degrees in the chart supports my right anticipations. However I falsely predicted that plasma ketone was highest 1-3 hours after the repast it is really higher while fasting to instantly after the repast. I predicted plasma insulin would be highest instantly after the repast when it is 1-3 after.

Application
1. During exercising. adrenaline and noradrenaline are released from the adrenal myelin. Epinephrine and noradrenaline have the same consequence on plasma glucose degrees as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is of import during exercising.

Epinephrine stimulates the dislocation of animal starch and glucose in the liver which so raises the degree of blood sugar. The glucose secreted so is used by the organic structure in times of emphasis or times when we need the excess energy or concentrate such as when exerting. Norepinephrine is basically the same thing nevertheless this is administered unlike adrenaline that is natural. 2. The symptoms of diabetes mellitus include high plasma glucose degrees and diabetic acidosis ( blood pH lessenings due to increasing degrees of ketones ) . Explain how diabetes causes these symptoms. Diabetess mellitus is a status where either you cant bring forth adequate insulin. your organic structure cant use the insulin that was produced. or in conclusion it is a combination of both all of these things play a factor in glucose and ketone degrees.
