Definitions:

CAM Plant

Plant that carries out crassulacean acid metabolism; carbon is initially fixed into organic acids at night in the reaction of CO2 and phosphoenolpyruvate, catalyzed by PEP carboxylase; during the day the acids break down to yield CO2, which enters the Calvin cycle. Compare with C3 plant and C4 plant.

Calvin Cycle

A series of biochemical redox reactions that take place in the stroma of chloroplasts in photosynthetic organisms and is a light-independent reaction.

Carbohydrate

Organic compounds consisting of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1, serving as a major energy source for the body.

RuBP

Ribulose bisphosphate, a molecule that plays a crucial role in the carbon fixation phase of photosynthesis.
