SNAB Light independent photosynthesis

What is the primary location for the light independent stage of photosynthesis?

• Thylakoid membrane

• Stroma of the chloroplasts

• Cytoplasm

• Outer membrane of the chloroplast

Which molecules are essential for the Calvin cycle to proceed?

• Glucose and Fructose

• ATP and reduced NADP

• Water and Oxygen

• Oxygen and Carbon Dioxide

What is the main purpose of the light independent reactions in photosynthesis?

• To absorb sunlight

• To synthesize organic compounds from carbon dioxide

• To convert light energy to chemical energy

• To produce oxygen

What is the significance of the light dependent reactions to the Calvin cycle?

• They convert CO2 to oxygen for the Calvin cycle.

• They produce glucose for the Calvin cycle.

• They absorb carbon dioxide used in the Calvin cycle.

• They provide ATP and NADPH needed for the Calvin cycle.

What is the role of the enzyme Rubisco in the Calvin cycle?

• It reduces GP to TP.

• It splits glucose into two three-carbon compounds.

• It helps in the regeneration of ATP.

• It catalyzes the fixation of CO2 to RuBP.

What does GP stand for in the context of the Calvin cycle?

• Glucose phosphate

• Glycerate 3-phosphate

• Glycolysis phosphate

• Glycerol phosphate

Which compound does carbon dioxide initially combine with in the Calvin cycle?
