If we use ribulose-5-phosphate that has been labeled with 14C isotope at the Carbon 1 position in the carbon reactions (of the Calvin Cycle), on which carbon of 3-PG should we see the labeled C atom appear? Explain.

Suppose ribulose-5-phosphate, labeled with "C in carbon 1, is used as the substrate in dark reactions. In which carbon of 3PG will the label appear?

Write a balanced reaction describing the biological oxidation of organic matter (use a formula for the organic matter of CH2O) to carbon dioxide by denitrifying bacteria (use nitrate reduction to nitrogen gas as the electron accepting process).  How many grams of nitrate are needed for the complete oxidation of 1 gram of organic matter according to your balanced reaction above?

3) The overall reaction for photosynthesis is: 6CO₂ + 6H₂O + ATP C6H₁2O6+ 60₂ (or more accurately 2x C₂H603) a. On this diagram identify where each of these reactants and products are found. b. Why don't you see the water or oxygen in this diagram? C. We can find the electrons from the water on here, where are they?
