AP Biology Photosynthesis and Cellular Respiration

Front

How is cellular respiration related to photosynthesis?

Back

Respiration is the opposite of photosynthesis.

Front

Where do the light reactions occur in photosynthesis?

Back

The light reactions occur in the thylakoid membrane.

Front

Where do the dark reactions (Calvin Cycle) take place?

Back

The dark reactions take place in the stroma.

Front

What molecule is released during the Kreb's cycle?

Back

Carbon Dioxide (CO2) is released during the Kreb's cycle.

Front

What is the main job of the electron carriers in cellular respiration?

Back

Transport electrons and hydrogen atoms to the electron transport chain.

Front

Where does the carbon come from that is used to form glucose in photosynthesis?

Back

The carbon comes from CO2 in the air.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are the two main stages of photosynthesis?

Back

The two main stages are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
