1. Rhodopsin is a light-sensitive pigment in the retina of the eye that is responsible for vision in dim light.
视紫红质是眼睛视网膜中对微弱光线产生反应的感光色素。
2. The absorption of light by rhodopsin triggers a cascade of chemical reactions that result in the transmission of visual signals to the brain.
视紫红质对光的吸收引发了一系列化学反应，最终传递了视觉信号到大脑。
