AP Biology Photosynthesis

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars from carbon dioxide.

Front

What role do pigments other than chlorophyll play in photosynthesis?

Back

Pigments other than chlorophyll absorb different wavelengths of light, allowing for a broader spectrum of light energy to be captured.

Front

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

Back

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

Front

How many sugar molecules are produced from every six molecules of carbon dioxide that enter the Calvin cycle?

Back

One sugar molecule is produced from every six molecules of carbon dioxide.

Front

What is released as a by-product of photosynthesis when water molecules are split?

Back

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

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 role of chlorophyll in photosynthesis?

Back

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

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.

Front

What is the source of the oxygen produced during photosynthesis?

Back

The oxygen produced during photosynthesis comes from the splitting of water molecules.

Front

What is the relationship between light intensity and the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis typically increases until it reaches a saturation point.
