CP Chapter 9 Photosynthesis

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells.

Front

How is energy released from ATP?

Back

Energy is released when a phosphate group is removed from ATP.

Front

What are the three components of ATP?

Back

ATP consists of adenine, ribose sugar, and three phosphate groups.

Front

What is the role of thylakoids in photosynthesis?

Back

Thylakoids are membrane-bound structures in chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the stroma?

Back

The stroma is the fluid-filled space inside chloroplasts where the light-independent reactions (Calvin cycle) take place.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is a carrier of electrons and hydrogen ions, used in the Calvin cycle to produce glucose.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require sunlight to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to drive the light-dependent reactions of photosynthesis.
