AP Biology- Photosynthesis

What is one function of the other pigments  besides chlorophyll, in the chloroplast?

• to block damaging wavelengths of light
• to absorb different wavelengths than the chloroplasts
• to provide different colors to the leaves
• to transfer energy to a separate photosystem beside the one using chlorophyll a and b.

What is the primary function of the Calvin cycle?

• regenerate ATP for use in the light reactions of photosynthesis
• produce carbon dioxide for use in the light reactions of photosynthesis
• produce oxygen by oxidizing water
• produce simple sugars from carbon dioxide

Photosynthesis goal is to

• convert light energy into glucose energy

• use light energy to make oxygen gas

• convert sugar energy into ATP

• convert sugar energy into oxygen gas

Rubisco is important in which step of photosynthesis

• energizing the electrons in chlorophyll

• carbon fixation when CO2 is connected to RUBP during calvin cycle

• regeneration phase as RUBP is made during calvin cycle

• reduction of the carbon chain during the calvin cycle
