Light Independent Reactions in Photosynthesis
How do ATP and NADPH connect light-dependent and light-independent reactions in photosynthesis?
ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions.
What is one role of ATP in the light-independent reaction of photosynthesis?
ATP supplies the energy to produce glucose and other carbohydrates.
Which is required for the light-dependent reactions in photosynthesis to occur?
H2O
What is required for both the light-dependent and light-independent reactions to proceed?
NOT CO2 energy
Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?"
NOT Light intensity has an impact on the rate of photosynthesis.
Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis?
NOT RuBP
Which compound is produced during regeneration?
RuBP
Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis?
The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Which statement about the light-independent reactions in photosynthesis is true?
They comprise the Calvin cycle.
Which process occurs during the light-dependent reactions in photosynthesis?
Water molecules are split.
Which is the first step in the scientific method?
ask a question
Which is required for the light-independent reactions in photosynthesis to occur?
carbon dioxide
In which type of environment are plants most likely to use a C4 pathway of carbon fixation?
hot and dry
In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen. 6CO2 + 6H2O ® C6H12O6 + 6O2 Which component could be added to complete this chemical equation?
light energy
During reduction, 3-PGA reacts with ATP and NADPH. What does ATP contribute to the reaction?
phosphate group
What is the source of the carbon dioxide that is used in photosynthesis?
the atmosphere
