AP Bio Insta-Review Topic 3.5: Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Reactions and the Calvin Cycle.

Front

Where do the Light Reactions occur?

Back

The Light Reactions occur in the thylakoid membranes of chloroplasts.

Front

What is produced during the Light Reactions?

Back

During the Light Reactions, ATP and NADPH are produced, along with oxygen as a byproduct.

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of chloroplasts.

Front

What is the main purpose of the Calvin Cycle?

Back

The main purpose of the Calvin Cycle is to convert carbon dioxide into glucose using ATP and NADPH produced in the Light Reactions.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and is essential for the Light Reactions of photosynthesis.

Front

What is the significance of oxygen production in photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms and contributes to the Earth's atmosphere.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration breaks down glucose to release energy for cellular activities.

Front

What are the inputs of photosynthesis?

Back

The inputs of photosynthesis are carbon dioxide, water, and light energy.
