Question
Chapter 50.3, Problem 4CC
Summary Introduction
To determine: The similarities between the two photo systems that is; the retina in eye and chlorophyll in plant.
Concept introduction:
Retina absorbs the light which is helps in conversion of “cis retinal to the trans retinal”. This conversion paves the way for further reaction through which the action potential is generated which helps in visualizing the object.
In chlorophyll, photosystem II is generally used in utilizing the light energy and converting it into utilizable energy.
