Experimenters injected bark scorpion venom into mouse neurons and measured how many action potentials were generated after the venom was introduced.

Is it possible that the venom could be affecting the activity of a voltage-gated potassium channel?

What effect could the venom have on a voltage-gated potassium channel to produce this result?

### Figure Description for Educational Website #### Panel A: Action Potential Traces - **Species Compared:** - *M. musculus* (top row) - *O. torridus* (bottom row) - **Experimental Conditions:** - Control (first column) - Exposure to 2 µg/ml Venom (second column) - Exposure to 10 µg/ml Venom (third column) - **Graph Details:** - **Y-axis:** Membrane potential (mV), with a scale of 40 mV per division. - **X-axis:** Time in seconds (2s intervals). - Both species show traces of action potentials. - For *M. musculus*, exposure to venom increases the frequency of action potentials. - For *O. torridus*, venom exposure results in reduced action potential frequency compared to control. #### Panel B: Bar Graph of Action Potential Frequency - **Species and Conditions:** - *M. musculus* and *O. torridus* under control, 2 µg/ml, and 10 µg/ml venom conditions. - **Y-axis:** - Number of action potentials recorded. - **X-axis:** - The two species, with bars representing different conditions for each species. - **Observations:** - *M. musculus* shows increased action potential frequency with venom concentration, peaking at 10 µg/ml. - *O. torridus* shows a reduced number of action potentials compared to *M. musculus*, and frequency decreases slightly with venom concentration. - **Bar Graph Key:** - White bars: Control - Light gray bars: 2 µg/ml Venom - Dark gray bars: 10 µg/ml Venom This figure illustrates how different species react to varying concentrations of venom in terms of neural activity.
