Mature erythrocyte cannot utilise glucose because they lack

Options

A. Golgi complex
B. Enzymes
C. Mitochondria
D. Nucleus

Answer

**Step-by-Step Solution:**

1. **Understanding Erythrocytes**: Erythrocytes, commonly known as red blood cells (RBCs), are specialized cells in the blood responsible for transporting oxygen.

2. **Mature Erythrocyte Characteristics**: In their mature form, erythrocytes lack several organelles that are typically found in other cell types. These include:
- Nucleus
- Mitochondria
- Ribosomes
- Centrosomes

3. **Role of Mitochondria**: Mitochondria are known as the powerhouse of the cell. They are responsible for cellular respiration, where glucose is broken down to produce ATP (adenosine triphosphate), the energy currency of the cell.

4. **Glucose Utilization**: Since mature erythrocytes lack mitochondria, they cannot perform aerobic respiration, which is necessary for utilizing glucose to produce ATP.

5. **Conclusion**: Therefore, the reason mature erythrocytes cannot utilize glucose is that they lack mitochondria.

**Final Answer**: Mature erythrocytes cannot utilize glucose because they lack mitochondria.
