Which of the following is NOT a reactant of the dark reactions?

• NADPH
• ATP
• Oxygen
• Carbon dioxide

What happens to NADPH and ATP after they are used in the Calvin Cycle?

• they recycle back to the light reactions
• they are used to make G3P

What does NADPH do? 

• carries electrons to the Calvin cycle
• carries electrons to the ETC

Which of the following best describes photosynthesis?

• Photosynthesis converts radiant energy into chemical energy.
• Photosynthesis produces carbohydrates.
• Plants need ATP, oxygen, water, nutrients, and chlorophyll to complete photosynthesis.
• Plants use mitochondria, water, and carbon dioxide to make sugar.

Photosynthetic organisms require which 2 inorganic substances

• water and glucose
• water and oxygen
• water and nitrogen
• water and carbon dioxide

Plants can use the oxygen they produce during

• DNA replication
• Photosynthesis
• cell respiration
• protein synthesis
