AP Biology Photosynthesis Flashcard

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 main products of the light reactions of photosynthesis?

Back

The main products of the light reactions are ATP, NADPH, and oxygen.

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 Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed and converted into glucose using ATP and NADPH produced in the light reactions.

Front

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

Back

The carbon used to form glucose comes from carbon dioxide (CO2) in the air.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the function of accessory pigments in photosynthesis?

Back

Accessory pigments, such as carotenoids, absorb different wavelengths of light than chlorophyll and help capture additional light energy for photosynthesis.

Front

What is produced during the light-independent reactions of photosynthesis?

Back

Sugar (glucose) is produced during the light-independent reactions, also known as the Calvin Cycle.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of the light reactions of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

How do plants absorb light for photosynthesis?

Back

Plants absorb light through chlorophyll and other pigments located in the chloroplasts, which capture light energy.
