PhotoSynthesis

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-dependent reactions and the light-independent reactions (Calvin cycle).

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 is produced by the splitting of water during the light-dependent reactions?

Back

Oxygen is produced by the splitting of water during the light-dependent reactions.

Front

Where does the carbon used to form glucose come from?

Back

The carbon used to form glucose comes from CO2 in the air.

Front

How does an increase in CO2 levels affect photosynthesis?

Back

An increase in CO2 levels in the air would most likely increase the rate of photosynthesis.

Front

What role does NADP+ play in photosynthesis?

Back

NADP+ acts as an electron carrier, transporting electrons during the light-dependent reactions.

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, which is essential for the light-dependent reactions.

Front

What are the products of the light-dependent reactions?

Back

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

Front

What is the significance of ATP in photosynthesis?

Back

ATP provides the energy required for the Calvin cycle to convert carbon dioxide into glucose.
