Question

below. - house mouse - grasshopper mouse fraction of sodium current 1.0 0.5 0.0 -5 -4 -3 -2 -1 logvenom (mg/ml) based on these data, what effect do you think the venom is having on the grasshopper mouse? the venom is blocking voltage - gated sodium channels. the venom is opening voltage - gated potassium channels. the venom is blocking voltage - gated potassium channels. the venom is opening voltage - gated sodium channels.

Explanation:

As the log[venom] concentration increases, the fraction of sodium current in the grass - hopper mouse decreases. Voltage - gated sodium channels are responsible for the influx of sodium ions during an action potential. A decrease in sodium current is likely due to the venom blocking these channels.

Answer:

The venom is blocking voltage - gated sodium channels.
