Hey guys, just need a little bit of help with this one,
The product of photosynthesis must undergo a three-stage process for the slug to access the energy in the
product.
b. Name and give a brief description of each of these stages.
So I know the three stages are Glycolosis, Krebs Cycle and Electron Transport Chain and I know that Glycolosis is where Glucose is converted to Pyruvate and 2 ATP are produced and with the Krebs how it is converted to CO2.
I'm just wondering, with the ETC, how does joining Hydrogen with Oxygen, produce 32-34 ATP?

Hydrogen ions pass along cristae, giving off electrons as they pass through cytochromes. This creates a proton gradient,In the in between the membranes which allows the conversion of Adp+pi to ATP
Then the spent hydrogen is met by 02, final
Acceptor, which forms h2o

Do we need to know that much detail for unit 3 bio?
I was thinking the same thing, all I knew was that electrons pass along cytochromes and somehow that makes ATP

the Krebs how it is converted to CO2.
Be careful with this statement, I assume you were referring to the pyruvate? Pyruvate undergoes decarboxylation in the matrix of the mitochondria before the krebs cycle which results in not pyruvate but acetylcoA entering the krebs cycle.

ATP synthase is the channel allowing the proton motive force thing.
