Comparison of
Reactants and
Products
Reactants: glucose, oxygen (later),
Reactants: water, carbon dioxide
Products: water, carbon dioxide, ATP
Products: glucose, oxygen
Comparison of
Pathways
Initially, glucose is broken down into two
3-carbon sugars. These are further broken
down to carbon dioxide, with ATP being
produced, and water (using up oxygen)
released.
Initially, sunlight is used to produce ATP and
NADPH, which are then used to build carbon
dioxide up into a 3-carbon intermediate. These
3-carbon intermediates can be converted into
other carbohydrates.
