Patients of diabetes have glucose in urine because
(a) Glucose is not absorbed from GF
(b) Glucose is absorbed from GF
(c) Glandular cells secreted glucose in GF
(d) Concentration of glucose is more in GF as compared to its normal amount

Options

A. Glucose is not absorbed from GF
B. Glucose is absorbed from GF
C. Glandular cells secreted glucose in GF
D. Concentration of glucose is more in GF as compared to its normal amount

Answer

To solve the question regarding why patients with diabetes have glucose in their urine, we can analyze each option provided:

1. **Understanding the context**: Patients with diabetes often experience a condition known as glycosuria, where glucose is present in the urine. This occurs due to issues with glucose metabolism and reabsorption in the kidneys.

2. **Analyzing the options**:
- **(a) Glucose is not absorbed from GF**: This option suggests that glucose is not reabsorbed at all. However, in diabetes, glucose is present in the glomerular filtrate (GF) but is not completely reabsorbed due to high levels.
- **(b) Glucose is absorbed from GF**: This option implies that glucose is being absorbed. While some glucose may be absorbed, in diabetes, it is not sufficient to prevent glucose from appearing in the urine.
- **(c) Glandular cells secreted glucose in GF**: This option is incorrect because glucose is not secreted into the GF by glandular cells; rather, it is filtered from the blood.
- **(d) Concentration of glucose is more in GF as compared to its normal amount**: This option correctly identifies that in diabetes, the concentration of glucose in the GF is elevated, which leads to incomplete reabsorption and results in glucose being excreted in the urine.

3. **Conclusion**: The correct answer is **(d) Concentration of glucose is more in GF as compared to its normal amount**. This high concentration prevents the kidneys from reabsorbing all the glucose, leading to its presence in the urine.

### Step-by-step Solution:
1. **Identify the condition**: Recognize that diabetes can lead to glycosuria, where glucose is found in the urine.
2. **Evaluate each option**: Analyze what each option states about glucose absorption and secretion.
3. **Determine the correct reasoning**: Understand that in diabetes, the high concentration of glucose in the GF overwhelms the reabsorption capacity of the kidneys.
4. **Select the correct answer**: Conclude that option (d) is the correct explanation for the presence of glucose in the urine of diabetic patients.
