Photosynthesis

Front

What colors of light does chlorophyll absorb?

Back

Chlorophyll absorbs red and blue light.

Front

Where do the light reactions of photosynthesis occur in the chloroplast?

Back

The light reactions occur in the thylakoid.

Front

What is the primary function of the light reactions in photosynthesis?

Back

The light reactions convert light energy to chemical energy in the form of ATP and NADPH.

Front

What is the overall chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Front

What is the interior space of the chloroplast called?

Back

The interior space of the chloroplast is called the stroma.

Front

What is the role of ATP in photosynthesis?

Back

ATP provides energy for the Calvin cycle, which synthesizes glucose.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH provides reducing power for the conversion of 3-PGA to G3P in the Calvin cycle.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light reactions of photosynthesis take place.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in the stroma of chloroplasts during photosynthesis, converting carbon dioxide into glucose.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is essential for photosynthesis as it captures light energy needed for the light reactions.
