GENERAL BIOLOGY-Q2-WEEK 3

Calvin cycle

The light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.

RuBisCO

An enzyme that catalyzes the fixing of atmospheric carbon dioxide during photosynthesis by facilitating the reaction between carbon dioxide and RuBP.

carbon fixation

The process of converting inorganic carbon (CO2) into organic molecules during the Calvin cycle.

light-independent reactions

Chemical reactions that convert carbon dioxide into glucose, occurring in the stroma of chloroplasts.

ribulose bisphosphate (RuBP)

An organic molecule involved in photosynthesis that reacts with carbon dioxide to form 3-PGA.

3-PGA (3-phosphoglycerate)

A three-carbon compound formed from the reaction between CO2 and RuBP in the Calvin cycle.

G3P (glyceraldehyde 3-phosphate)

A three-carbon compound produced during the reduction phase of the Calvin cycle, which can be used to form glucose.

regeneration of RuBP

The last stage of the Calvin cycle where RuBP is regenerated to allow for the continuation of carbon fixation.

ATP and NADPH

Energy carriers produced in light-dependent reactions that provide energy for the Calvin cycle.

importance of the Calvin cycle

It plays a crucial role in photosynthesis by converting carbon dioxide into glucose, thus sustaining life processes.
