Model Photosynthesis light and dark reactions

Front

What is the main purpose of photosynthesis?

Back

To make sugar (glucose) for energy.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is produced during the light-dependent reactions?

Back

ATP, NADPH, and Oxygen.

Front

What is the role of carbon dioxide (CO2) in photosynthesis?

Back

CO2 is a reactant used to produce glucose.

Front

What do ATP and NADPH provide for the light-independent reactions?

Back

They provide the energy and reducing power needed to convert CO2 into glucose.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the significance of oxygen produced in photosynthesis?

Back

Oxygen is a byproduct that is essential for the respiration of most living organisms.

Front

What are light-dependent reactions?

Back

Reactions that capture light energy to produce ATP and NADPH.

Front

What are light-independent reactions also known as?

Back

Calvin cycle.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.
