The Light-Dependent Reactions – Principles of Biology ...
Photosynthesis can be split into two sets of reactions: Light-dependent reaction. Light-independent reaction - a.k.a the Carbon fixation reaction/Calvin-Benson Cycle. 1. The Light-Dependent Reaction . Overview. Light energy is converted into chemical energy and stored as ATP. Light splits H2O into H+ and O and electrons. O2 is released into atmosphere. H+ combines with NADP+ to form NADPH. The ...

Circle the letter of each sentence that is true about the light-dependent reactions. Correct the false statements. High-energy electrons move through the electron transport chain from photosystem II to photosystem I. Photosynthesis begins when pigments in photosystem I absorb light. The difference in charges across the thylakoid membrane provides the energy to make ATP. 20. What are the ...

(The light dependent reactions would shut down and no more ATP and NADP-H would be produced. When the available supplies of ATP and NADP-H are used up, the Calvin cycle would stop.) 20. One molecule of phosphoglyceraldehyde (= PGAL) contains more energy than three molecules of carbon dioxide. During the Calvin cycle (the light independent reactions) the low energy carbon atoms in …

The light-dependent reactions need sunlight. They use energy from this sunlight to produce energy-rich compounds, like ATP. The light-independent reactions use these energy-rich compounds to produce sugars from carbon dioxide. Complete the T-chart. Write the phrases in the box that belong in each side of the chart.

The light reactions do not require carbon dioxide, so the light reactions can take place when the stomata are closed. At night, when the evaporation rates are lower the stomata are open to allow the intake of carbon dioxide so the dark reactions can take place. In C3 plants the reactions can take place at the same time. In C4 plants, the reactions can also take place at the same time due to a ...
