Question

Is photosynthesis a reversible reaction?

Answer 1

I found a couple of sites that talk about photosynthesis being a reversible reaction. The idea in both sites is that the reaction in which plants produce O2 is essentially reversed when humans/other animals produce CO2; however, this is not the same thing as a reversible chemical reaction in which the products and reactants are in equilibrium and both reactions (forward and reverse) are occurring at the same time in the same system. I thinjk both of these sites is taking some liberties with the definition. I don't know what course you are taking but my answer is no. I think these two web sites are using two separate systems. Anyway, here is one of the sites for you to read.

Answer 2

Oh ok. Yep, that's what I originally thought, because aerobic respiration is the reverse. But when you mentioned that it had to occur at the same time in the same system, I think I'm beginning to understand a little more.

Thx and I will look at the website ^^
