Is photosynthesis irreducibly complex?
https://www.youtube.com/watch?v=ktXnLnUA8XA&t=892s

In photosynthesis, 26 protein complexes and enzymes are required to go through the light and light-independent reactions, a chemical process that transforms sunlight into chemical energy,  to get glucose as the end product, a metabolic intermediate for cell respiration.  A good part of the protein complexes is uniquely used in photosynthesis. The pathway must go all the way through, and all steps are required, otherwise, glucose is not produced. Also, in the oxygen-evolving complex, which splits water into electrons, protons, and CO2, if the light-induced electron transfer reactions do not go all the five steps through, no oxygen, no protons, and electrons are produced, no advanced life would be possible on earth. So, photosynthesis is an interdependent system, that could not have evolved, since all parts had to be in place right from the beginning. It contains many interdependent systems composed of parts that would be useless without the presence of all the other necessary parts. In these systems, nothing works until all the necessary components are present and working. So how could someone rationally say, the individual parts, proteins and enzymes, co-factors and assembly proteins not present in the final assemblage,  all happened by a series of natural events that we can call ad hoc mistake "formed in one particular moment without the ability to consider any application.", to then somehow interlink in a meaningful way, to form electron transport chains, proton gradients to " feed " ATP synthase nanomotors to produce ATP, and so on?  Such independent structures would have not aided survival. Consider the light-harvesting complex,  and the electron transport chain, that did not exist at exactly the same moment--would they ever "get together" since they would neither have any correlation to each other nor help survival separately? Repair of PSII via turnover of the damaged protein subunits is a complex process involving highly regulated reversible phosphorylation of several PSII core subunits. If this mechanism would not work starting right from the beginning,  various radicals and active oxygen species with harmful effects on photosystem II (PSII) would make it cease to function.  So it seems that photosynthesis falsifies the theory of evolution, where all small steps need to provide a survival advantage.


Essential parts of oxygenic photosynthesis

The photosynthesis pathway is interdependent and irreducible. Take any of the individual parts out, and the process ceases to function. Neither do most individual parts and proteins have any function, unless in this remarkable pathway. We can, therefore, infer that design explains best the origin of photosynthesis through a creator.

1. Lipid bilayer membranes are critical to the early stages of energy storage, such that photosynthesis must be viewed as a process that is at heart membrane-based. 4
2. Chlorophyll is an essential component of photosynthesis, which helps plants get energy from light. 1
3. The light-harvesting complexes, also called antenna complexes,  are essential for collecting sunlight and regulating photosynthesis 2
4. Photosystem II (PSII) is a key component of photosynthesis 2
5. The oxygen-evolving is responsible for catalyzing the oxidation of water to molecular oxygen in plants, algae, and cyanobacteria. 3
6. The cytochromeb6 f complex  is an essential player in noncyclic and cyclic electron flow 4
7. Plastocyanin is an essential member of photosynthetic electron transport and functions near PS I.  5
8.  PSI is necessary to provide the energy to reduce NADP+ to NADPH  6
9. Ferredoxin (Fd) proteins are required for the electron transfer process  from the bound Fe–S centers in the Photosystem I reaction center to NADP+. 4
10. Ferredoxin—NADP(+) reductase same as 9
11. In plants and photosynthetic bacteria, ATP synthase is essential for solar energy conversion and carbon fixation.


In a photovoltaic system, each part of the system has a specific function, which is essential and contributes to the whole system to achieve its pre-established goal, in this case, to produce electric energy. Solar panels play a central ingredient in the system. Neither do Solar panels have the function on their own, nor all other parts without Solar panels. They are interdependent. Nobody in its sane mind would construct a factory to produce Solar panels with no use, and without making all other parts, and a system map, a blueprint, how to bring all parts together to have a functional whole.

In photosynthesis, 26 protein complexes and enzymes are required to go through the light and light-independent reactions, a chemical process that transforms sunlight into chemical energy, to get glucose and fixed carbon to make glucose, its food of the organism as end products. A good part of the protein complexes is uniquely used in photosynthesis. The pathway must go all the way through, and all steps are required, otherwise, glucose is not produced. Also, in the oxygen-evolving complex, which splits water into electrons, protons, and oxygen, if the light-induced electron transfer reactions do not go all the five steps through, no oxygen, no protons, and electrons are produced, and no advanced life would be possible on earth.
