Which is a product of the light dependent reactions but NOT a reactant of the Calvin Cycle of photosynthesis?

carbon dioxide

NADPH

ATP

oxygen

Expert Solution

Ans:

Oxygen

Explanation: In both cyclic and noncylic electron transport, ATP is produced when high energy electron is transfer between electron carrier (Plastoquinone→Cytochrome b6f). NADPH is produced in final step of non-cyclic electron transport where NADP+ accepts electron from FNR (ferredoxin-NADP reductase) and reduced to NADPH + H+. This NADPH and ATP are consumed in Calvin cycle. NADPH is consumed in the conversion of 1,3 bisphophoglycerate to 3-phosphoglyceraldehyde. ATP are consumed in the conversion of 3-phosphoglycerate to 1,3 bisphophoglycerate and ribulose-5-phosphate to ribulose-1,5-bisphosphate conversion. The oxygen is produced in photolysis of water, does not used in Calvin cycle. CO2 are not produced in light dependent reactions, it absorbed by plant from atmosphere.

The Calvin cycle is sometimes referred to as the dark reactions, even though light is required for flux to be maintained. Describe the two primary mechanisms that regulate Calvin cycle enzymes so that they are most active in the light.

(a) For overall chemical reactions that describe an equilibrium condition or balance between reactant and product species, explain why thermodynamic equilibrium constants cannot be determined solely from the ratios of forward and backward rate constants. (b) Why is it required for chemical reactions to be balanced in both mass and charge in order to apply thermodynamic principles (i.e., equilibrium constants or free energies of reaction)?
