Photosynthesis AP Biology

Front

What are photosystems made of?

Back

Photosystems are made of chlorophyll.

Front

Which of the following does NOT contribute to ATP production during the light reaction?

Back

NADPH donating electrons.

Front

What is FALSE about the Calvin cycle?

Back

The Calvin cycle does not produce carbon dioxide.

Front

What is the function of a C4 plant regarding CO2?

Back

C4 plants store CO2 in a separate cell from their photosynthetic cell during the day.

Front

What effect does an increase in CO2 in the air have on photosynthesis?

Back

An increase in CO2 in the air would most likely increase photosynthesis.

Front

Define 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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily in the blue and red wavelengths, and converts it into chemical energy.

Front

What is the primary product of the Calvin cycle?

Back

The primary product of the Calvin cycle is G3P (glyceraldehyde-3-phosphate), a three-carbon sugar.

Front

What is photorespiration?

Back

Photorespiration is a process that occurs when the enzyme RuBisCO fixes oxygen instead of carbon dioxide, leading to a decrease in photosynthetic efficiency.
