The original formula takes one carbon atom ..
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. (Illustration adapted from P.J. Sellers et al., 1992.)

What happens to carbon atoms in photosynthesis
The carbon that is stored in hydrocarbons and considered as part of the world’s carbon store amounts to about 4000GT. This is the estimate for all the carbon within all the Earth’s coal, oil, and natural gas. The formation of fossil fuels differs from the formation rock in that fossil fuels are derived almost wholly from organic matter. Though it is often assumed that the fossil fuels that we so enjoy today are composed of the carbon that was once the dinosaurs of yesterday, this assumption is wrong. The majority of fossil fuels available were formed from the remains of flora and fauna from times before the dinosaurs. This idea helps one conceptualize just how old this stored energy is. This essentially ancient sunlight is the product of photosynthesis that occurred upwards of three hundred million years ago.
How does a carbon atom travel through photosynthesis
Influences are felt which relate to the number of carbon atoms, unsaturation and conformation of the fatty acids, others mainly to the triacylglycerol structure itself.

In the West, the conception of the physical universe and humanity’s ability to manipulate it has remarkably changed in the past few thousand years, which has been a tiny fraction of humanity‘s journey on Earth. Thousands of years ago, the Greek philosophers argued that the universe was comprised of atoms and the void, and Pythagoras taught that Earth orbited the Sun. during the same era. Hundreds of years later, a Greek mathematician and engineer, , described the first steam engine and windmill and is typically credited as the inventor, but the actual inventors are lost to history. Western science and technology did not significantly advance for the next millennium, however, until . The reintroduction of Greek teachings, and the pursuit of their energy technologies, ultimately led to the and revolutions.
