BIOL 1108 Study Guide - Midterm Guide: Light-Independent Reactions, Redox, Carbon Cycle
Document Summary
Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air. Photosynthesis is the source of all food we eat, oxygen that we breathe, and fuels for eating and transportation. Photosynthesis can occur practically anywhere, but it occurs most readily in the platic zone of the ocean and terrestrial environments that are both moist and warm, such as tropical rain forests. The photosynthetic electron transport chain takes place on specialized membrane. The three reactions that compose the calvin cycle are carboxylation, reduction, and regeneration. The incorporation of carbon dioxide is catalyzed by the enzyme rubisco. In the carboxylation step of the carbon cycle, carbon dioxide is added to rubp (a. Nadph is the reducing agent of the calvin cycle. Reduction of 3 pga involves the donation of a phosphate group to 3 pga by. The regeneration of rubp re requires atp.
