WebA. Respiration runs the biochemical pathways of photosynthesis in reverse. B. Photosynthesis stores energy in complex organic molecules, whereas respiration releases it. C. Respiration is anabolic and photosynthesis is catabolic. D. ATP molecules are produced in photosynthesis and used up in respiration. WebCAM plants are the plants, which fix carbon dioxide by CAM pathway or Crassulacean acid metabolism. It was first discovered in the plants of the Crassulaceae family. They are … WebFeb 1, 2024 · Photorespiration, also known as oxidative photosynthetic carbon cycle or C2 photosynthesis, is a process found in normal C3 plant respiration. Here, the enzyme RuBisCO uses O 2 as a substrate instead of CO 2. This alternative pathway leads to the loss of fixed carbon, wastes energy, and decreases sugar synthesis.
