No, blood glucose concentration is regulated by negative feedback. When blood sugar levels are too high, the alpha particles in the pancreas' islets of Langerhans signal the pancreas to produce more insulin, which regulates the sugar level by stimulating the liver and other body cells to absorb more glucose at convert it into either glycogen or fat. This lowers the blood sugar concentration. If it were positive feedback, high blood sugar levels would encourage the production of more glucose to increase the blood sugar concentration.
What else can I help you with?
Negative feedback with increase in blood glucose?
negative feedback can increase the concentration of glucose in the blood stream. if the blood glucose levels are too low, alpha cells will produce glucagon which causes the liver to break glycogen down into glucose. it is then released into the blood stream which increase the blood glucose levels.if it is too high, the beta cells will produce insulin which causes the liver and muscle cells to form glycogen from glucose. In addition, other cells are encouraged to use glucose in cell respiration rather than fats.both the beta and alpha cells are produced from the pancreas.
What is the main carbohydrate in plasma?
The main carbohydrate in plasma is glucose. It is the primary energy source for the body's cells and is constantly regulated to maintain stable levels in the blood.
Is respiration a negative feedback?
Yes, respiration is regulated by negative feedback mechanisms to maintain balance of oxygen and carbon dioxide levels in the body. When carbon dioxide levels increase, it triggers an increase in breathing rate to expel excess carbon dioxide and bring levels back to normal.
What hormone is involved in blood glucose regulation?
There are two hormones that regulate blood glucose levels. One is insulin. This horemone "carries" glucose into the cell. No glucose and the cell starves and the glucose levels get higher in the blood. The second hormone takes glucose out of liver storage and increases the glucose in the blood. These two are a feedback mechanism that keeps the levels in a normal range.
When blood glucose level rises the pancreas secretes insulin and as a result blood glucose level declines when blood glucose level is low the pancreas secretes glycogen and as a result blood glucose?
When blood glucose levels rise, the pancreas secretes insulin, which helps cells take up glucose from the blood, lowering blood glucose levels. When blood glucose levels are low, the pancreas secretes glucagon, which stimulates the liver to release stored glucose into the bloodstream, raising blood glucose levels back to normal.
What controls when a hormone is secreted?
There is no single answer to this question, but one common aspect is that most hormone release is in somehow regulated by a negative feedback system. For example a hormone produces an effect that in turn inhibits the same hormone's release. There are also positive feedback loops as in the rise of glucose acting to increase insulin release which then lowers glucose levels.
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
What is insulin primarily regulated by?
Insulin secretion is primarily regulated by blood glucose levels. When blood glucose levels rise after a meal, beta cells in the pancreas release insulin to help cells uptake glucose for energy production.
Is control of blood glucose levels a negative feedback?
If high blood pressure is at play then a negative feedback system would reverse this. Through this negative feedback the stimulus of increased pressure is reversed or decreased by decreasing heart rate which decreases the blood pressure. If low blood pressure is at play the negative feedback system would also be appropriate because your body needs to reverse this stimulus. Your heart rate would increase to increase blood pressure. NOTE: Positive Feedback system enhances or further intensifies the stimulus so we would not want that for blood pressure. This is seen for birth contractions. You want to intensify contractions to enable the baby to get out of the canal. However, usually you need some external event to turn off the positive feedback or it could be fatal. In this case the baby is born so that stops the contractions.
What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
How does the pancreas control the levels of sugar in your blood?
Negative feedback, opposing to positive feedback, stops a reaction, rather than promoting a reaction. Insulin, secreted from the pancreas, is a hormone that regulates blood sugar levels, and it tells your body to make more glucose for your blood. When you eat, the glucose comes in and adds more to what you already have. The glucose level of your body rises, telling the pancreas to stop secreting insulin and telling your body to stop making more glucose, producing a negative feedback.
Is insulin negative feedback or positive feedback?
Insulin is a hormone produced by the beta cells in the pancreatic islets of Langerhans that stimulates glycolysis and increase glucose uptake in muscle and adipose tissue; therefore, it maintain homeostasis in the body by decreasing blood sugar level when it is high. It shows a negative feedback because the response negates the stimulus to maintain homeostasis.
Negative feedback with increase in blood glucose?
negative feedback can increase the concentration of glucose in the blood stream. if the blood glucose levels are too low, alpha cells will produce glucagon which causes the liver to break glycogen down into glucose. it is then released into the blood stream which increase the blood glucose levels.if it is too high, the beta cells will produce insulin which causes the liver and muscle cells to form glycogen from glucose. In addition, other cells are encouraged to use glucose in cell respiration rather than fats.both the beta and alpha cells are produced from the pancreas.
What is a positive feedback mechanism?
A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment
What organ releases glucose to help maintain normal blood glucose levels in between meals?
The liver releases glucose into the bloodstream to help maintain normal blood glucose levels in between meals. This process is regulated by hormones like insulin and glucagon.
What organ regulates blood sugar level in the body?
Insulin controls glucose levels in the blood. Those having diabetes or suppose to become diabetic, their insulin secretion is erratic and are to take insulin injection to stable the glucose level in the blood.
What is the main carbohydrate in plasma?
The main carbohydrate in plasma is glucose. It is the primary energy source for the body's cells and is constantly regulated to maintain stable levels in the blood.
