light-sensitive proteins

Light-sensitive proteins are molecules found in cells that can detect and respond to light. They contain special structures that change when exposed to specific wavelengths of light, triggering biological responses. These proteins play key roles in processes like vision, circadian rhythms, and plant growth. For example, in the human eye, photoreceptor proteins convert light into electrical signals sent to the brain, enabling us to see. In plants, they help regulate growth based on daylight. Overall, light-sensitive proteins act as biological light sensors, allowing organisms to adapt and function effectively in their environments.
