The answer

Barry Shell answered on October 11, 1999

Rhodopsin is a pigment that when hit by light (photons) will cause one or more biological reactions such as the movement of an electron to create, for instance, ATP, or adenosine triphosphate, a common energy transfer molecule used in many biological systems. This energized molecule can then be used by the bacteria for any energy requiring process such as moving or growing.
