The output of the Calvin cycle is G3P (Glyceraldehyde 3-p).  The calvin cycle makes 6 of these , but only one leaves to be used by the plant.  What happens to the other 5, and why is this necessary?

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase can be used more than once.   Calvin cycle can be organized into 3 basic stages.  During the         stage, the enzyme          catalyze the fixation of           by ribulose biphosphate.  For each CO2 and RuBP, two molecules of         get formed.  During the                    phase,  and            are used to convert  6 molecules of 3-PGA into G3P.  During the              phase, one molecule of G3P leaves the Calvin cycle to contribute to the formation of other compounds needed by the plant.  The remaining 5 molecules of G3P regenerate              .  This enables the system to fix more             .   3-phosphoglycerate                         NADPH                                       fixation ATP                                             pyruvate                                       reduction…

When a leaf on an oak tree absorbs 15,440 photons, how many glyceraldehyde-3-phosphate molecules can be produced by the Calvin cycle?

The absorption spectrum of chlorophyll a differs from the actionspectrum of photosynthesis. Explain this observation.
