If a plant is removed from its natural environment and exposed to 100 percent CO2 composed of the radioisotope 14C, which of the following will not occur? Select one: a. The rate of photorespiration will remain unchanged. b. The sugars synthesized by the plant will be radioactive. c. The oxygen released will also be radioactive. d. All the carbon molecules in the RuBP molecules will eventually become 14C. e. Rubisco will eventually contain 14C.
Plant roots are adapted as storage organ( such as potatoes and carrots)Typically photosynthesize during the summer and remain dormant underground during winter. Explain how sugar transport in such a plant would be different during summer, when the plant is photosynthesizing and in the spring when new growth is coming up
What happens during the regeneration stage of the Calvin Cycle? Energy from ATP and electrons from NADPH are used to reduc 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose) The remaining G3P molecules that have not exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue Oxygen is produced through this process The enzyme Rubisco attaches to CO2 to RuBP, causing the formation of molecules of 3-phosphoglycerate
