Reduction reactions are crucial in converting light energy into chemical energy during the process of photosynthesis.
In photosynthesis, carbon dioxide is reduced to form glucose.
The Calvin cycle includes several reduction steps where NADPH donates electrons.
Reduction and oxidation reactions (redox reactions) are coupled; when one substance is reduced, another is oxidized.
ATP and NADPH produced in the light-dependent reactions provide the energy and electrons needed for the reduction steps in the Calvin cycle.
