Question
Chapter 19, Problem 13P
Interpretation Introduction
Interpretation:
To decipher how the light harvesting complexes enhance the efficiency of photosynthesis.
Concept introduction:
Light-harvesting complexare involved in the light reaction and are organized in two discretePhotosystems - Photosystem I and Photosystem II. Both the photosystems comprise of same pigment combination except a chlorophyll a molecule. Thus, the light-harvesting system is known as antennae
