Photosynthesis - Honors Biology 2024

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 (light-independent reactions).

Front

What occurs during the light reactions of photosynthesis?

Back

During the light reactions, light energy is converted into chemical energy in the form of ATP and NADPH, and oxygen is released as a byproduct.

Front

Where do the light reactions take place?

Back

The light reactions take place in the thylakoid membranes of chloroplasts.

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 plays a crucial role in the light reactions of photosynthesis.

Front

What are the products of the light reactions?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose using ATP and NADPH produced in the light reactions.

Front

What is the ultimate source of energy for photosynthesis?

Back

The ultimate source of energy for photosynthesis is the Sun.

Front

Which molecule is not required for the light reactions to occur?

Back

Carbon dioxide (CO2) is not required for the light reactions to occur.

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.
