18 Questions
What is the result of the light reaction in photosynthesis?
Production of ATP and NADPH
Where does the dark reaction occur in the chloroplast?
Stroma
What is the role of ATP and NADPH in the Calvin cycle?
To drive the reaction and convert CO2 into glucose
What is the product of the Calvin cycle?
Glyceraldehyde-3-phosphate (G3P)
What is the purpose of stomata in plants?
To capture carbon dioxide
What is the outcome of photosynthesis in terms of its importance?
All of the above
What is the effect of increased light intensity on the rate of photosynthesis?
It increases the rate of photosynthesis
What is the ideal concentration range of carbon dioxide for efficient photosynthesis?
300-400 PPM
What is the temperature range at which photosynthesis occurs efficiently?
25-35°C
What is the consequence of water deficiency on photosynthesis?
It leads to the closure of stomata to conserve water
What is the byproduct of photosynthesis in certain bacteria?
No oxygen as a byproduct
What is the formula for the photosynthesis reaction?
6CO2 + 6H2O → C6H12O6 + 6O2
What is the primary energy source required for photosynthesis?
Solar energy
What is the byproduct of the light-dependent reactions in photosynthesis?
ATP and NADPH
In which part of the chloroplast do the light-independent reactions take place?
Stroma
What is the process of fixing carbon dioxide into organic compounds in the Calvin cycle?
Carbon fixation
What is the end product of the Calvin cycle in photosynthesis?
Glucose
What is the overall equation for photosynthesis?
6CO2 + 6H2O —> C6H12O6 + 6O2
Test your knowledge of the dark reaction of photosynthesis, a light-independent process that occurs in the stroma of the chloroplast, where sugar molecules are formed from water and carbon dioxide molecules. Learn about the chemical equation, NADPH, ATP, and the role of chloroplasts. Review the concepts of carbon-fixing reaction and light-independent process.
