Term
Light Dependent Reactions
Definition
In photosynthesis the reactions in which light energy is captured and used in production of ATP and NADPH. In plants this involves the action of two linked photosystems.
Term
Light Independent Reactions
Definition
In photosynthesis the reactions of the Calvin cycle in which ATP and NADPH from the light-dependent reactions are used to reduce CO2 and produce organic compounds such as glucose. This involves the process of carbon fixation or the conversion of inorganic carbon (CO2) to organic carbon (ultimately carbohydrates).
Term
Calvin Cycle
Definition
a series of biochemical redox reactions that take place in the stroma of chloroplasts in photosynthetic organisms.
Term
Carbon Fixation
Definition
The conversion of CO2 into organic compounds during photosythesis; the first stage of the dark reactions of photosynthesis, in which carbon dioxide from the air is combined with riulose 1, 5-bisphosphate.
