The mysterious world of quantum biology: Why are quantum effects so critical to life?
In their quest to understand the nature of life, scientists have discovered a fascinating intersection: quantum biology. This is a field that studies how quantum mechanics and its theoretical chemistry affect biology, especially those biological processes that cannot be accurately described by the laws of classical physics. Understanding fundamental quantum interactions is crucial because they determine the properties of higher-level organization in biological systems. Many biological processes involve energy conversion and are based on quantum mechanical properties, which give life a mysterious balance.
Many biological processes involve energy conversion and are based on quantum mechanical properties, which give life a mysterious balance.
The rise of quantum biology has triggered a rethinking of quantum phenomena in life processes, including four major life processes: enzymatic reactions, sensory processes, energy transfer, and information coding. Although this field is still in its exploratory stage, physicists have already begun to consider the application of quantum mechanics in biology as early as the 20th century. Therefore, the theoretical soil of quantum biology has been rooted in the long river of history and is constantly developing.
Quantum tunneling in enzyme-catalyzed reactions
Enzymes are thought to use quantum tunneling to transfer electrons. This means that the quaternary structure of some proteins may develop in a way that allows quantum entanglement and coherence phenomena to persist, which is crucial for quantum tunneling in living organisms. Quantum tunneling is the ability of a subatomic particle to pass through a potential barrier due to the principle of wave-particle duality. These particles such as electrons and protons can travel through energy barriers without violating the laws of physics due to their wave nature.

In biological energy processing networks, the transfer of protons is considered key, and quantum effects often play a role in the proton distribution sites. The transition from quantum elements (such as particles) to macroscopic phenomena (such as biochemical substances) is defined by semiclassical methods. In biology, electron transfer and proton tunneling play important roles in processes such as photosynthesis and cellular respiration.
Quantum basis of sensory processes
Olfaction, as a sense, involves the reception and detection of chemicals, a process that still holds many mysteries. Shape theory suggests that certain odor molecules trigger olfactory receptors through specific shapes, while quantum theory posits that olfactory receptors can actually detect the frequencies produced by the vibrations of the molecules. This reflects the potential role of quantum effects in biological senses and shows the mystery of the microscopic world in life processes.
In vision, quantum effects facilitate the process of converting light signals into action potentials, a process known as phototransduction. During this process, photons interact with pigment molecules in photoreceptors, and this efficient transduction process once again reminds us of the wonders of the quantum world.
The role of quantum effects in energy transfer and photosynthesis
Photosynthesis is an important biological process that enables biological cells to use sunlight to synthesize organic matter and transfer energy based on quantum effects. During the light reaction phase of photosynthesis, photons are absorbed by membrane-bound photosystems, followed by energy transfer, a process that undergoes high-speed and high-efficiency quantum behavior. Scientists use quantum coherence phenomena to understand the mechanism of energy transfer from light capture to reaction centers in photoreactions.
During the light reaction phase of photosynthesis, photons are absorbed by membrane-bound photosystems, completing the transfer of energy.
Quantum effects in these processes are the product of evolution, enabling organisms to use their tiny and delicate structures in the best way to achieve optimal energy conversion efficiency. As our research deepens, we gradually realize how to apply the principles of quantum mechanics to different fields, including quantum communications and cryptography.
Future Outlook
As research on quantum biology deepens, the scientific community begins to think about the revolutionary changes it may bring in medicine and biotechnology. Quantum phenomena not only underlie biological processes, but may also become a driving force for future technological advances. Various explorations in quantum biology have shown the connection between life and the microscopic world, which makes us wonder whether future scientific breakthroughs will open up a new perspective for us to understand life?
