The processes listed below represent major chemical pathways in

photosynthesis. Respond to statements 80–84 with reference to these five processes. a. light-dependent reactions b. chemosynthetic reactions c. carbon dioxide fixation d. Calvin-Benson cycle e. C4 pathway D 80. This leads to the formation of a glucose-6-phosphate from two molecules of phosphoglyceraldehyde. M 81. In this process carbon dioxide is incorporated first into an unstable intermediate compound and then into phosphoglycerate. E 82. This yields NADPH as well as ATP. M 83. This is a carbon-fixing system that precedes the Calvin-Benson cycle in some plants. M 84. PGAL molecules are formed from the reaction of PGA molecules with ATP and NADPH in this pathway.
