What is the sensor and integrator and effector of the blood glucose feedback loop?
The sensor in a negative feedback loop monitors the state of the variable, in this case blood glucose. For blood glucose, the sensor as well as the integrator is the Islets of Langerhans, since it contains the alpha and beta cells. Alpha cells produce glucagon, a hormone that acts on the liver to release more glucose into the blood. Beta cells produce insulin, which controls the uptake of glucose into the cells. The effectors respond to the sensor's messages, and act to maintain a variable. The effectors for blood glucose are the cells which take in glucose, as well as the liver.
What is the glucose sensor in B-cells Why?
glucokinase. glucokinase has a high km(low affinity for glucose) so glucokinase only phosphorylates glucose when blood glucose is high, such as after a meal. As such, it makes sense that this would be sensor for B-cells
How many units of insulin for a Blood glucose level of 278?
It depends on what kind of insulin you are taking....for example: insulin can be rapid acting, short acting, intermediate acting or long acting.
What is the difference between NovoLog insulin and Novolin insulin for type 1 diabetes?
Novolin is a short-acting insulin, taken for correcting high blood glucose and before or after eating. Novolog is a long-lasting insulin, taken to stabilize blood glucose between the times that you take your short-acting doses.
What are method for measuring blood glucose?
Common methods for measuring blood glucose include using a glucose meter to test a drop of blood from a finger prick, continuous glucose monitoring systems that provide real-time glucose readings through a sensor inserted under the skin, and laboratory blood tests that measure glucose levels in a blood sample taken from a vein.
Which renal structure transport glucose?
The proximal convoluted tubule in the kidney is responsible for reabsorbing glucose from the filtrate back into the bloodstream. This ensures that glucose is not lost in the urine and helps maintain normal blood sugar levels.
What are the structure of the human blood?
Plasma (which is pretty much water), platelets, minerals, hormones, carbon dioxide, glucose, and of course red blood cells.
Is glucose a blood sugar?
Correct, glucose is a blood sugar.
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.
Is a reading of 137 of concern for blood glucose?
A fasting blood glucose of 137 is a concern. A random blood glucose of 137 is not a concern.
What is a glucose blood test for?
To test for the amount of sugars (glucose) in the blood.
What are the new instrument used to measure blood glucose?
You can get your blood glucose level checked at your local doctor's office, pharmacist, or by purchasing a blood glucose machine. You can buy them online, at your doctor's office, or at your pharmacist.
