Assume you have a suspension of non-water dwelling photosynthetic cyanobacteria. using your knowledge of photosynthesis and the calvin cycle, predict whether the levels of ribulose-1,5-bisphosphate and 3-phosphglycerate will increase or decrease in photosynthetic cells given the altered changes in conditions. assume that the system has reached a steady state prior to the change in condition. provide your answer as increase or decrease. a) carbon dioxide levels are drastically reduced. ribulose-1,5-bisphosphate: 3-phosphoglycerate: b) an inhibitor of photosystem ii is added to the system. ribulose-1,5-bisphosphate: 3-phosphoglycerate: c) light is changed to a wavelength of 550 nm. ribulose-1.5-bisphosphate: 3-phosphoglycerate:
