 Photoreceptor protein

Photoreceptor proteins are specialized proteins that are sensitive to light and play a crucial role in the conversion of light signals into biochemical signals in various organisms. These proteins are essential for processes like vision in animals, photosynthesis in plants, and regulating circadian rhythms in all living organisms. There are several types of photoreceptor proteins, each with distinct functions: 1. **Rhodopsins**: These are found in the retina of animals and are critical for detecting light, allowing for vision.
