glucose is excreted in urine in Diabetes when the blood sugar level is beyond normal and insulin is not enough or not doing the job of transporting sugar to its target organ.
The main reason is that because the kidneys cannot absorb all of the excess glucose in the body. This excess glucose spills into the urine, accompanied by water and electrolytes ions necessary for the cells to regulate the electric charge and flow of water molecules across the cell membrane. Hence this causes frequent urination to get rid of the additional water drawn into the urine and excessive thirst to trigger replacement of lost water.

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 happens to the concentration of glucose in urine as the number of glucose carriers increase?
As the number of glucose carriers increase, the concentration of glucose in the urine will decrease. This is because more glucose is being reabsorbed by the kidneys back into the bloodstream, reducing the amount of glucose that gets excreted in the urine.
How glucose is excreted?
Glucose is primarily reabsorbed in the kidneys rather than excreted. In healthy individuals, nearly all glucose filtered through the kidneys is reabsorbed in the proximal tubules. However, when blood glucose levels exceed a certain threshold, such as in uncontrolled diabetes, excess glucose is excreted in the urine. This process occurs due to the saturation of glucose transporters, leading to glucosuria.
What is excreted from the kidneys?
Urine is excreted from the kidneys.
Glucose can be elevated in the blood of a diabetic person Relate this information to glucose in the urine and glucose carriers?
When blood glucose levels are high in a diabetic person, the kidneys may not be able to reabsorb all the glucose, leading to glucose spilling into the urine (glucosuria). Glucose carriers, such as SGLT2 in the kidney tubules, may become saturated, causing excess glucose to be excreted in the urine. This can be an indication of uncontrolled diabetes and a mechanism for reducing high blood glucose levels.
What chemical is made from ammonia that excreted in the urine?
Urea is the chemical made from ammonia that is excreted in the urine. Our body converts ammonia, a waste product of protein metabolism, into urea in the liver. Urea is then filtered by the kidneys and excreted in the urine.
What is the end-product excreted in urine from protein metabolism?
The end-product excreted in urine from protein metabolism is urea.
What liquids carry the urea that is excreted?
Urea is predominantly carried in urine, which is produced by the kidneys and excreted through the urinary system. In the bloodstream, urea is carried in the form of urea nitrogen and is filtered by the kidneys to be excreted in urine.
Why isn't glucose normally found in urine?
Glucose is not in Urine because the body transforms all the extra glucose into fat and stores in the the body instead of excreting it with urine. Glucose can be seen in urine in uncontrolled diabetes millitus, when the blood glucose level is higher than the kidneys threshold of glucose reabsorbtion, then the extra glucose gets excreted with urine instead of getting reabsorbed by the kidneys.
How long does it take for water to be excreted as urine?
It typically takes about 2-3 hours for water to be excreted as urine after drinking it.
Urea is produced by the and excreted by the?
Urea is produced by the liver and is excreted by the kidneys as a part of urine.
Where is urine excreted in the body?
Urethra
