Light energy is absorbed by chlorophyll which..
Is oxidised and the electrons pass between proteins in the thylakoid membranes,
Generating ATP and…
Reducing NADP while…
Photolysis of water supplies H ions and electrons to replace the ones lost from chlorophyll.

Ribulose bi-phosphate reacts with carbon dioxide…
To make GP which is reduced by NADP and ATP…
To produce a carbohydrate – triose phosphate which…
May be converted to other carbohydrates or…
Used to regenerate ribulose bi-phosphate (needing some ATP).

Glucose is phosphorylated with ATP and…
Splits into a 3C sugar which…
Is oxidised to Pyruvic acid…
Reducing NAD and generating…
Some ATP.
This is in cytoplasm.

The pyruvate loses a C as carbon dioxide and…
Reacts with coenzyme A to form acetyl coenzyme A which…
Enters the mitochondria and react with a 4C intermediate to…
Form a 6C acid which is oxidised in a series of steps until the 4C intermediate is remade…
This produces reduced NAD, FAD and some ATP.

Lots of ATP until…
The H ions and electrons are picked up by oxygen producing water.
