Abstract

Recently, there has been a growing interest and controversy about the role that quantum effects might play in some biological processes. Here, two heavily studied examples of such effects are discussed: The impact of quantum coherence in the efficiency of energy transport in photosynthesis and the radical pair mechanism in the magnetic compass of birds. In this study, a review of theoretical and experimental work that has aided understanding these effects, provides the ground for discussion regarding their biological relevance. The findings of this work suggest that quantum coherence might be crucial for the efficiency of energy transfer in photosynthetic systems, whereas more evidence are needed to support the idea of a magnetic compass based on the radical pair mechanism. In addition, gaps in the current research in these two fields are identified and recommendations for further work are made.
