The correct response is:
The hydrogen in glucose is recycled when water is formed.
During cellular respiration, glucose (which contains hydrogen) is broken down to produce energy, and one of the byproducts of this process is water, which is formed by the incorporation of hydrogen ions.
The correct response is:
6
During photosynthesis, six molecules of water (6 H₂O) are used to produce one molecule of glucose (C₆H₁₂O₆) along with six molecules of oxygen (6 O₂) as a byproduct. This is based on the overall balanced equation for photosynthesis:
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
The correct response is:
It was recycled when glucose was formed.
During photosynthesis, the hydrogen atoms from the water (including the radioactive hydrogen) are incorporated into glucose molecules. Thus, the radioactive hydrogen is effectively "recycled" in the formation of glucose.
