A new perception about photosynthesis
- 1. A new perception about Photosynthesis Dr. Purushottam Lal Assistant Professor in Botany Govt. College, Dholpur 328001 bansiwal.purush@gmail.com
- 2. WELCOME TO PHOTO-BIOLOGY DISCLAIM: I am NOT a Photo biologist
- 3. What is Photosynthesis ? - Sequence of Reactions - Energy Transformation (Photon to Carbohydrates) - The Ultimate Power Behind
- 5. RC Diversity: The Hardwares
- 7. Photosystems
- 8. General Scheme - C2 - C4 - CAM
- 10. Deeper Look: Inductive Resonance - Energy transfer from Antenna to RC - NOT e-flow (Excitation energy) - Highly efficient one (billionth fraction of second) How can be such efficiency is achieved ? Particle Vs Wave nature of Exiton
- 11. - Energy transfer follows more than one routes simultaneously - Wave like behaviour of “exitons”
- 12. We have obtained the first direct evidence that remarkably long-lived wavelike electronic quantum coherence plays an important part in energy transfer processes during photosynthesis,” said Graham Fleming (Quantum Secrets of Photosynthesis Revealed, April 12, 2007 issue of the journal Nature). “This wavelike characteristic can explain the extreme efficiency of the energy transfer because it enables the system to simultaneously sample all the potential energy pathways and choose the most efficient one.” Experimental Detection

- 14. Some Basic Principles : Matters (life) can be viewed at Quantum level (Sub-Atomic level) : Dual nature of Matter – Particle & Wave : At Quantum level, Super-Position occurs : Objects exist at more than one places at a single time
- 15. : Matters (life) can be viewed at Quantum level (Sub-Atomic level)
- 16. : Dual nature of Matter – Particle & Wave Heisenbergs-Uncertainty-Principle
- 17. : At Quantum level, Super-Position occurs 200 Seconds = 10,000 Years of Supercomputer
- 18. Quantum supremacy - Powered by a Sycamore, it completed a task in 200 seconds that, by Google's estimate, would take 10,000 years on the world's fastest supercomputer
- 20. : Objects exist at more than one places at a single time तू जहाां जहाां चलेगा मेरा साया साथ होगा…
