"You were accidentally served a salad at your Aunt Tutu's house over Thanksgiving that contained leaves of an experimental spinach plant. All we know is that the plant had received a treatment of 3H (tritium) and that it (3H) has been found in the sweat (H2O) released from your body as a by-product of aerobic cellular respiration. Provide a plausible but detailed explanation as to how the tritium made its way into your H2O? Be specific in your explanation. Hint: The plant came from the lab of Dr. Van Niel.

Help Please!! I don't understand the question!!

Well if we consider the equation of cellular respiration

C6H12O6+6O2=6CO2+6H2O

the glucose is turned into water. What has happened here is that the 3H got mixed in with the glucose somewhere along the line, and its coming out as water in sweat

The question is designed to make you track where the water comes from in aerobic cellular respiration. I'd hate to give you the answer, so I'll give you some clues. Go back to your notes, book, whatever you are using for your assignment, and find the sections that break down the three parts of cellular respiration. Then figure out which part of cellular respiration produces water and why. (In other words, work backward: "The water was produced during ________________ stage of cellular respiration, and is a result of __________________, etc"...something to that effect).

Hope this helps some.

Check out some diagrams of photosynthesis to see if hydorgen could have been incorporated into plant tissues and were subsequently ingested. Then refer to glycolysis, the citric acid cycle, and electron transport. They should be in your text. Look for sources of hydrogen, that enter the cycles and then leave as by-products after bonding with oxygen to form water.

do you want someone to explain the question, or just answer it for you? i think the question is straightforward. how did the 3H go from the spinach leaf into your sweat?

Look up the Kreb's Cycle, CAM Plants, and Mitochrondrial Metabolism. After you refresh your memory on that you should know the answer.
