When the blood glucose level exceeds about 160 - 180 mg/dl (8.9 - 10 mmol/l), the proximal tubule becomes overwhelmed and begins to excrete glucose in the urine. This point is called the renal threshold of glucose (RTG) hope that this answer might help you and it is taken from wikipedia.

What is renal threshold of glucose?
Renal threshold is what happens when there is an overabundance of glucose in the body, the blood glucose levels will then get above 170mg/100ml (normal is 70mg/100ml).
Whenever the plasma glucose concentration exceeds the renal plasma threshold?
it shows in urine.
What happens when the plasma glucose cocentration exceeds the renal plasma threshold?
It will cause the change of the alpha and beta cells
What has the author Charles Beaverstock written?
Charles Beaverstock has written: 'Effect of renal threshold on urine glucose and patient acceptance and maintenance of home blood glucose monitoring'
What is meant by surpassing the renal threshold?
Type your answer here... It is nothing but surpassing the renal threshold of an individual above the threshold which was normal to that person in certain period.
What processes prevent glucose from being excreted in the urine?
Glucose reabsorption in the kidneys prevents it from being excreted in urine. This reabsorption process occurs in the renal tubules, where glucose is actively transported back into the bloodstream. If blood glucose levels are too high, such as in diabetes, the renal threshold for glucose reabsorption may be exceeded and glucose can then be excreted in the urine.
What is the blood glucose level above which glucose starts to appear in urine?
First of all, WHAT KIND OF QUESTION IS THAT?But, whatever. The renal threshold, where glucose levels exceeds the capacity to return the glucose into the blood (glycosuria) is about 10 mmol/l (180 mg% ).
How high does the serum glucose have to be for the threshold for glucose to be achieved?
180
Does the renal artery contain higher levels of glucose than then renal vein?
No, the renal artery carries blood with higher levels of oxygen and nutrients to the kidneys, while the renal vein carries blood with waste products, including urea and carbon dioxide, away from the kidneys. Glucose is typically reabsorbed in the renal tubules, so the levels of glucose are lower in the renal vein compared to the renal artery.
What is the pathway of a glucose molecule from the renal artery to the renal vein?
Pathway of glucose and other molecules from renal artery to renal vein is the following . 1 renal artery , 2 arcuate artery ,3 interlobular artery , 4 afferenr renal arteriole , 5 glomerulus , 6 efferent renal arteriole , 7 peritubular network of capillaries including vasa recta , 8 interlobular vein , 9 arcuate vein and 10 renal vein .
Is the reneal thershold decrease with age?
In some cases, the renal threshold does decrease with age. But not everyone will have a decrease.
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.
