Photorespiration and Reduction in Photosynthesis Efficiency

• Name the reaction in which plants require no light.

  The dark reaction of C-4 photosynthesis occurs inside of specialized parts of leaf cells in the leaf called the bundle sheath, which exclude the presence of O2. Because there is no oxygen present photorespiration does not occur.

• Photorespiration

  Then under shaded conditions (like in a corner). Then finally in the dark. In each case, this will alter the light being met by the plant, and you can find the balance between light needed for photosynthesis while minimizing photorespiration.

• Energy acquisition

  When the weather gets hot and dry the stomata close to conserve water. Unfortunately, this also keeps out the CO2. Much photosynthetic efficiency is lost in C3 plants this way.

• On Energy

  I know that if insufficient water was available to participate as a reactant in the process of photosynthesis, the plant converts to photorespiration where no cellular energy is produced.

• Photosynthesis in corn and tomato plant

  This leads to photorespiration, which leads to a net loss of carbon and nitrogen from the plant rather than photosynthesis.

• Comparing and Contrasting Photosynthesis and Aerobic Cellular Respiration

  # Photosynthesis requires carbon dioxide, releases oxygen, involves reduction, and stores energy. # Both photosynthesis and cellular respiration are metabolic pathways.

• Understanding photosynthesis.

  The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyanobacteria and their relatives, which are responsible for a major part of photosynthesis in oceans.

• This is a CAM (Crassulacean acid metabolism) plant

  the stomata close and CO2 stored from the previous night is released to allow for photorespiration to occur.

• Photosynthesis and Cellular Respiration Questions

  Photosynthesis is a redox reaction ( meaning oxidation-reduction) just like cellular respiration. Photosynthesis use light energy to reduced C02 to sugar when electrons and hydrogen ions are added to it in a process of reduction.
