Photosynthesis can be divided into two steps: the light-dependent reactions and the Calvin cycle.
Which of the following correctly describes the overall process of the light-dependent reactions?
During the light-dependent reactions, carbon fixation occurs
The light-dependent reactions occur in the stroma of choloroplasts
Light energy is converted into chemical energy in the form of ATP and NADPH
ATP and NADPH are used to make carbohydrates
Which of the following best describes how the light-dependent reactions and Calvin cycle function together?
The Calvin cycle uses ATP and NADPH generated by the light reactions to synthesize carbohydrates.
The Calvin cycle uses ATP and NADPH generated by the light reactions to break down carbohydrates.
The Calvin cycle generates ATP and NADPH to excite electrons during the light reactions.
The Calvin cycle produces ATP and NADPH to drive the formation of an electrochemical gradient during the light reactions.
What can the glucose made during photosynthesis be used for?
Cellular respiration
Synthesis of other organic compounds
Osmosis
Stored as starch for later
Photosynthesis
