AP Biology: Unit 3 Review (CED)

Front

Where did photosynthesis first evolve?

Back

Photosynthesis first evolved in prokaryotic organisms.

Front

What are the products of the light-dependent reactions of photosynthesis?

Back

The products of the light-dependent reactions of photosynthesis are NADPH and ATP.

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

What is the function of the electron transport chain between Photosystem II and Photosystem I?

Back

The function is to establish an electrochemical gradient of protons.

Front

In order to maintain order and power cellular processes, what must occur?

Back

Energy input must exceed energy loss.

Front

What is the primary role of chlorophyll in photosynthesis?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, converting CO2 into glucose.

Front

What is the role of ATP synthase in cellular respiration?

Back

ATP synthase synthesizes ATP from ADP and inorganic phosphate using the energy from the proton gradient.

Front

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

Back

The electron transport chain is crucial for generating ATP through oxidative phosphorylation.

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).
