In photosynthesis, what is the ultimate source of electrons? What are the benefits of this molecule in terms of its toxicity and the cost of the plant to obtain it?

In photosynthesis, which of the following is NOT true about the light-dependent (“light”) reaction? In photosynthesis, which of the following is NOT true about the light-dependent (“light”) reaction? Glucose is synthesized from CO2 and water during the light-dependent reaction The light-dependent reaction converts light energy to chemical energy stored in ATP  The light-dependent reaction (non-cyclic) captures electrons in NADPH  Light-excited electrons in chlorophyll provide the energy for ATP production None of the other four answers (All are true of the light-dependent reaction)

Define the following terms:

Draw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.
