Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin Cycle?
ATP and NADPH
Which of the events listed below occurs in the light reactions of photosynthesis
Light is absorbed and funneled to reaction-center chlorophyll a
As a research scientist, you measure the amount of ATP and NADPH consumed by the Calvin cycle in 1 hour. You find 30,000 molecules of ATP are consumed, but only 20,000 molecules of NADPH. Where did the extra ATP molecules come from?
Cyclic electron flow
Cyclic electron flow may be photoprotective (Protective to light-induced damage). Which of the following experiments could provide information on this phenomenon?
Use mutated organisms that can grow but that cannot carry out cyclic flow of electrons and compare their abilities to photosynthesize in different light intensities against those of wild-type organisms
In a plant leaf, the reactions that produce NADH occur in
Neither the light reactions nor the Calvin cycle
Which of the following statements best represents the relationships between the light reactions and the Calvin cycle?
The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, and NADP+ to the light reactions
Why are C4 plants able to photosynthesize with no apparent photorespiration?
They use PEP Caboxylase to initially fix CO2
Compared to C3 plants, C4 plants
Can continue to fix CO2 even at relatively low CO2 concentrations and high oxygen concentrations
