AP Biology Photosynthesis

Front

What wavelengths of light are most effective for photosynthesis?

Back

Blue and red wavelengths are most effective for photosynthesis.

Front

What is the primary function of the light reactions of photosynthesis?

Back

The primary function of the light reactions is to produce NADPH and ATP.

Front

What is released as a direct by-product of splitting water molecules during photosynthesis?

Back

Oxygen is released as a direct by-product of splitting water molecules.

Front

Why do C4 plants store carbon dioxide?

Back

C4 plants store carbon dioxide to keep stomata open for less time, preventing excess transpiration.

Front

Which of the following is NOT a product of the light reactions: Oxygen, NADPH, ATP, or Glucose?

Back

Glucose (Sugar) is NOT a product of the light reactions.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily in the blue and red wavelengths, to drive the photosynthesis process.

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

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.
