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 much glucose is filtered in the kidney every day?
Approximately 180 grams of glucose are filtered by the kidneys every day. However, almost all of this glucose is reabsorbed back into the bloodstream through the process of renal reabsorption, and very little is excreted in the urine.
What happens to glucose which the nephron along with a filtrate?
Glucose in the filtrate is reabsorbed from the nephron back into the bloodstream through the walls of the renal tubules. This process occurs mainly in the proximal convoluted tubule, where glucose transporters actively reabsorb glucose to maintain its concentration in the blood. If there is excess glucose that cannot be reabsorbed, it may be excreted in the urine.
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.

If one says that the clearance value of glucose is zero what does this mean?
A clearance value of zero for glucose means that no glucose is being excreted or removed from the body within the specified time frame. This could indicate a problem with glucose metabolism or kidney function, as glucose should normally be cleared from the body through urine.

What are the three products of photosynthesis?
Glucose, which is stored in the root system of the plant. Oxygen and water molecules are formed also, but they are wastes and are excreted into the atmosphere through the leaves.

Why was glucose excreted in urine?
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 does sweat empty out of your skin through?
Excess glucose can be excreted in both the urine - through the urethral meatus, and also through the bowels, in the form of stool - through the rectum and anus.
What is excreted from the kidneys?
Urine is excreted from the kidneys.
Effect of saline on blood glucoes level?
In general not much correlation at all except in the kidneys. The kidneys will filter out both sodium and glucose but then reabsorb it later on in the tubules. When they get reabsorbed they do so together. If there is more glucose than sodium, then some of that excess glucose will get excreted in the urine bringing the overall blood glucose level down to about 140 mg/dl. That situation is frequently associated with diabetes mellitus.
What is in the blood of untreated diabetes?
The most common abnormal substituent in the blood of a diabetic is a large amount of glucose. While glucose is normally in the blood (around 80-100 mg/dL), diabetics lack the hormone insulin which promotes glucose absorption into the cells. As a result, the glucose remains in the blood and is excreted through the urine due to the inability for the glomerular filtration membrane to weed out the massive amount coming through.
