Photosynthesis 3

Where do the light-dependent reactions occur? 

• thylakoid membrane
• stroma
• mesophyll
• mitochondria

Where does the Calvin Cycle occur?

• thylakoid
• stroma
• lumen
• mitochondria

True or False.   The calvin cycle can happen at night.

• true
• false

Which term is the part of photosynthesis when light energy is captured and transferred to a molecule, such as ATP?

• light- independent reactions
• cellular respiration
• light- dependent reactions
•  photosynthesis

This molecule helps add a phosphate do a depleted energy molecule.

• PS 2
• PS 1
• Electron Transport Chain
• ATP Synthase

What is the first stop in photosynthesis process?

• Photosystem I
• Photosystem II
• Electron Transport Chain
• stroma

Use the diagram to answer the question. Which chemical is an electron carrier molecule?

• H₂O
• carbon dioxide
• NADP⁺
• oxygen

Is ADP or ATP more like a fully charged battery, and why?

• ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.

What characteristic sets heterotrophs apart from autotrophs?

• Heterotrophs can be classified only as mammals.
• Heterotrophs use energy from the sun to make their own food.
• Heterotrophs obtain food from consuming other living or once-living things.
• Heterotrophs obtain food through the process of photosynthesis.

What is the function of NADPH and ATP?

• They absorb light
• The power the light-dependent reactions
• They are light-reflecting pigments
• They act as short-term energy storage
