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 in photosynthesis?

Back

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

Front

Which pigment is primarily responsible for absorbing light in plants?

Back

Chlorophyll is the primary pigment responsible for absorbing light in plants.

Front

What is the role of ATP in photosynthesis?

Back

ATP provides the energy needed for the Calvin cycle to synthesize glucose from carbon dioxide.

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.

Front

What is the equation for photosynthesis?

Back

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

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 of photosynthesis take place?

Back

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

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the red and blue wavelengths, which is essential for the light reactions of photosynthesis.

Front

What is produced during the light reactions that is essential for the Calvin cycle?

Back

NADPH and ATP produced during the light reactions are essential for the Calvin cycle.
