Multiple Choice

Which is the best description of the Light Reaction of photosynthesis?

• A) Chlorophyll absorbs solar energy, which shoots of electrons providing energy to carbon dioxide and water into glucose. Some energy in the form of ATP and NADPH is made along the way.
• B) Chlorophyll absorbs solar energy and shoots off an electron, which is transferred through a series of compounds, releasing a little energy (ATP) each time, and ending up in NADPH. Energy stored in ATP and NADPH provides fuel for the Calvin cycle.
• C) Carbon dioxide and water combine with chlorophyll to absorb solar energy. The carbon dioxide shoots of an electron which is transferred through a series of compounds, releasing a little energy (ATP) each time, and ending up in NADPH. Energy stored in ATP and NADPH provides fuel for the Calvin cycle.
• D) Water in the leaf absorbs solar energy and shoots off an electron, transferring it to chlorophyll, which is then passed through a series of compounds, releasing a little energy (ATP) each time, and ending up in NADPH. Energy stored in ATP and NADPH provides fuel for the Calvin cycle.
• E) When solar energy (light) strikes combined chlorophyll, carbon dioxide, and water, the carbon dioxide shoots off an electron, which is then passed through a series of compounds, releasing a little energy (ATP) each time, and ending up in NADPH. Energy stored in ATP and NADPH provides fuel for the Calvin cycle.
