Question

Most animals have neurons that respond to unfavorable environmental conditions by sending pain signals to the brain. For example, elevated CO₂ triggers an influx Na⁺ that opens voltage-gated Na channels to initiate an action potential. The naked mole-rat (Section8-2D), which lives in crowded underground colonies, has a voltage-gated Na⁺ channel that is inhibited by protons. Explain why this is advantageous.

Short answer

This allows the animals to tolerate the highly crowded colonies.

Step-by-step solution

Introduction

Hyaluronate interferes with the signaling pathwaythat promotes malignant transformation.

Advantageous of sending pain signals to the brain

Many animals have neurons that respond to adverse environmental circumstances by transmitting a pain signalto the cell. This channel protein is responsible for transmitting electric impulses in pain-sensing neurons. The inflow of is triggered by the increased concentration of .

The positively charged carbonic acid is attracted to the hydrogen ion because of this characteristic. is then converted tocarbonic acid, which dissociates into bicarbonate and protons. The stimulus signalling is deactivated by these protons. Higher concentrations induce pain signals, which are blocked by the proton. This enables the creatures to live in densely populatedsubterranean colonies.

Step 3:Conclusion

As a result, the creatures are able to withstand the densely populatedsubterranean nests.
