Increase in concentration of bicarbonate in blood plasma would result in increased

Options

A. ventilation of lungs
B. urination
C. ultrafiltration
D. salivation

Answer

**Step-by-Step Solution:**

1. **Understanding Bicarbonate in Blood Plasma:**
- Bicarbonate (HCO3-) is a key component in the transport of carbon dioxide (CO2) in the blood. It is formed when CO2 reacts with water (H2O) in the presence of the enzyme carbonic anhydrase, producing carbonic acid (H2CO3), which dissociates into bicarbonate and hydrogen ions (H+).

2. **Role of Bicarbonate in Carbon Dioxide Transport:**
- Approximately 70% of carbon dioxide is transported in the form of bicarbonate ions in the plasma. An increase in bicarbonate concentration indicates that more CO2 is being transported, suggesting higher metabolic activity in the body.

3. **Metabolic Activity and CO2 Production:**
- Increased metabolic activity leads to higher production of carbon dioxide as a waste product. This means that the body is producing more CO2, which needs to be expelled to maintain homeostasis.

4. **Need for Ventilation:**
- To remove the excess CO2 from the body, the respiratory system must increase its activity. This is achieved through ventilation, which involves increasing the rate and depth of breathing.

5. **Conclusion:**
- Therefore, an increase in the concentration of bicarbonate in blood plasma would result in increased ventilation of the lungs, leading to an increased respiratory rate to expel more CO2 and intake more oxygen.

**Final Answer:**
- Increase in concentration of bicarbonate in blood plasma would result in increased ventilation of the lungs.
