AP Biology: Unit 3 Review (CED)

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of chloroplasts.

Front

Where did photosynthesis first evolve?

Back

Photosynthesis first evolved in prokaryotic organisms.

Front

In the electron transport chain of cellular respiration, where is the electrochemical gradient of protons generated?

Back

The electrochemical gradient of protons is generated in the intermembrane space.

Front

Where does the electron transport chain take place?

Back

The electron transport chain takes place in chloroplasts, prokaryotic plasma membrane, and mitochondria.

Front

Where on an enzyme does the substrate bind?

Back

The substrate binds at the active site of the enzyme.

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to convert carbon dioxide into glucose using ATP and NADPH.

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

Front

What is the significance of the electron transport chain in cellular respiration?

Back

The electron transport chain is significant because it generates ATP through oxidative phosphorylation.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
