Photosynthesis Review

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 pigments involved in photosynthesis?

Back

The main pigments involved in photosynthesis are chlorophyll a, chlorophyll b, and carotenoids.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, and converts it into chemical energy.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP, NADPH, and oxygen are produced.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent reaction of photosynthesis that uses ATP and NADPH to convert carbon dioxide into glucose.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of the chloroplasts.

Front

What is the importance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.

Front

What is the equation for photosynthesis?

Back

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