Bio Review Sheet Photosynthesis
Photosynthesis enables plants to produce structural and metabolic substances that aid in
their survival. For example, much of the glucose produced by plants is converted to
cellulose; glucose may also be converted to other sugars and storage forms of
carbohydrates (i.e. starch).

Carbon dioxide and water, with the additional of energy from the sun, are used to produce
glucose and oxygen.
As the term photosynthesis suggests, the process involves 2 sets of reactions: photo,
meaning light, refers to the reactions that capture light energy and synthesis, which refers
to the reactions that produce a carbohydrate. These two sets of reactions that make up
photosynthesis are called light dependent and light independent reactions.
• In lightdependent reactions, light energy is trapped and used to generate two
highenergy compounds: ATP and NADPH.
• In lightindependent rea
