Title: Photosynthesis and collision theory
Post by: PandaxRules on November 04, 2020, 12:30:01 AM

Hello, I will try to keep this short.

I was up late and simply wondered if collision theory played a part in photosynthesis, What I'm asking is: photosynthesis and how collision theory occurs during the process.

I've thought this so far: The energy from the sun gives energy in order for the carbon dioxide and water to collide and react but without energy, at night this would not happen. I may be wrong so that's why I'm asking.

Thanks

Photosynthesis is much, much more complicated than that. It is not about just water and carbon dioxide, there is a huge system of molecules and enzymes at work. Whole process takes many steps, most of them not utilizing directly energy from the Sun. Most of these steps can be at least partially explained in terms of collision theory, but collision theory is a highly simplified model, that doesn't account for many phenomena present in photosynthesis process chemistry.

You are right that at night photosynthesis stops.

Photosynthesis is a good example of biochemical coupling of an unfavorable process to a source of energy.

Photosynthesis isn't that simple.

A part of it is:

So, a lot more complex than the 2-reactant 2-product equation you're taught at school.
