Midterm Biology Review

Front

What is the name of the pigment molecule that absorbs light energy and makes plants green?

Back

Chlorophyll is the pigment molecule that absorbs light energy and gives plants their green color.

Front

What are the two products of the light reactions that are needed for the Calvin cycle?

Back

The two products are NADPH and ATP.

Front

What is the interior space of the chloroplast called?

Back

The interior space of the chloroplast is called the stroma.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are oxygen (O2) and glucose (C6H12O6).

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

What is the role of ATP in the Calvin cycle?

Back

ATP provides the energy needed for the conversion of carbon dioxide into glucose during the Calvin cycle.

Front

What is the significance of the stroma in chloroplasts?

Back

The stroma is the site where the Calvin cycle occurs, allowing for the synthesis of glucose.

Front

What is the difference between light reactions and the Calvin cycle?

Back

Light reactions convert light energy into chemical energy (ATP and NADPH), while the Calvin cycle uses that energy to synthesize glucose.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
