When exposed to yellow light, which neuron expression may be true for animal X?

When exposed to yellow light, which neuron expression may be true for animal X?

• A. Neuron A expresses ion channel S that is gated by blue light
• B. Neuron B expresses ion channel W that is gated by blue light
• C. Neuron A expresses ion channel W that is gated by yellow light
• D. Neuron B expresses ion channel S that is gated by yellow light

Answer: (C)

Choosing the option indicating that Neuron A expresses ion channel W that is gated by yellow light is correct because it aligns with the premise of a potential physiological response to yellow light exposure. In the context of light sensitivity and neuronal response, certain ion channels are specifically tuned to react to different wavelengths of light. When an animal is exposed to yellow light, it would make sense for certain neurons to express channels that are responsive to that specific wavelength. Ion channel W being gated by yellow light implies that when yellow light is present, it can trigger the opening of this channel, allowing ions to flow through and possibly leading to an excitatory response in Neuron A. This could be part of a mechanism for visual processing or other sensory functions related to the presence of yellow light. The other options suggest responses to blue light, which would not be expected in this scenario as the focus is on the reaction to yellow light. Therefore, it reinforces the idea that Neuron A’s activity and ion channel expression are specifically attuned to the conditions presented in the question.
