- It was recycled into glucose.
The correct answers are:
1) The carbon in carbon dioxide is recycled as glucose. (The carbon in carbon dioxide is fixed by plants during photosynthesis and converted into glucose, which can be used for energy or stored for later use.)
2) The hydrogen in glucose is recycled as water. (During cellular respiration, the hydrogen atoms from glucose combine with oxygen to form water, which is then eliminated from the plant through transpiration or other means.)
3) 6 molecules of water are recycled into one molecule of glucose during photosynthesis. (During photosynthesis, plants use sunlight energy to combine 6 molecules of carbon dioxide with 6 molecules of water to produce one molecule of glucose and 6 molecules of oxygen.)
4) The radioactive hydrogen was recycled into glucose. (During photosynthesis, plants take up the radioactive water and incorporate the radioactive hydrogen into glucose, which allows scientists to track the movement and fate of the hydrogen within the plant.)
