Photosynthesis Equation

Post by kassia420 » Fri Nov 18, 2005 1:11 am

In the equation for photosynthesis, why is chlorophyll written above (or sometimes below) the arrow?

chlorophyll
6CO2 + 6H2O + light energy ------------> C6H12O6 + 602

Because it only catalyses the reaction. It allows it take place, is involved in the process but is not changed by the reaction itself.

Why so many people insist so much on the general equation of photosynthesis is beond my power of understanding. my teacher took 20 minutes to explain it to us, but she didn't even mention the cyclic electron transport.
To me, that equation is nothing more than an application of Hess's law

Does anyone know why there are 2 different equations representing photosynthesis?

6CO2 + 12H2O ---> C6H12O6 + 6O2 + 6H2O

6CO2 + 6H2O ---> C6H12O6 + 6O2

when in the first one you got 6 molecules of water that don't actually enter the reaction. they are just there necessary for the enzymes to be active
