Glucose is taken back from glomerular filtrate through

Options

A. active transport
B. passive transport
C. osmosis
D. diffusion

Explanation

To answer the question "Glucose is taken back from glomerular filtrate through," we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Glomerular Filtrate**:
- Glomerular filtrate is the fluid that is filtered from the blood through the glomerulus in the kidneys. It contains water, ions, glucose, amino acids, and other small molecules.

2. **Reabsorption Process**:
- The kidneys reabsorb essential substances from the filtrate back into the bloodstream. This process is crucial for maintaining the body's homeostasis.

3. **Location of Reabsorption**:
- The primary site for glucose reabsorption is the Proximal Convoluted Tubule (PCT) of the nephron.

4. **Mechanism of Glucose Reabsorption**:
- Glucose is reabsorbed from the filtrate in the PCT through a specific mechanism. This process requires energy.

5. **Type of Transport**:
- The transport of glucose from the glomerular filtrate back into the blood is primarily through **active transport**.
- Active transport involves the movement of molecules against their concentration gradient, which requires energy in the form of ATP.

6. **Conclusion**:
- Therefore, glucose is taken back from glomerular filtrate through **active transport** in the Proximal Convoluted Tubule (PCT).

### Final Answer:
Glucose is taken back from glomerular filtrate through **active transport**.
