Question:
Which is the best description of the Calvin Cycle of photosynthesis?
A. It is a cyclical series of reactions utilizing atmospheric carbon dioxide to produce carbohydrates.
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 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.
Photosynthesis:
Photosynthesis is the processes in plants that take carbon dioxide and makes carbohydrates as food for the plant. Photosynthesis is separated into two sets of reactions: 1) Light Reactions and 2) Dark Reactions (Calvin Cycle).
