Unit 3 Review

Front

What is the function of the electron transport chain?

Back

The electron transport chain is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions. This process generates a proton gradient that drives ATP synthesis.

Front

Where do mitochondria and chloroplasts contain electron transport chains?

Back

Both mitochondria and chloroplasts contain electron transport chains that are essential for cellular respiration and photosynthesis, respectively.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process by which ATP is formed as electrons are transferred through the electron transport chain and oxygen is reduced to water.

Front

Where does oxidative phosphorylation occur in the cell?

Back

Oxidative phosphorylation occurs in the inner membrane (cristae) of mitochondria.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH.

Front

Where does glycolysis take place?

Back

Glycolysis takes place in the cytosol of the cell.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is fixed into glucose.

Front

Where does the Calvin cycle occur?

Back

The Calvin cycle occurs in the stroma of chloroplasts.

Front

What is the pathway of electrons in the light reactions of photosynthesis?

Back

The pathway of electrons in the light reactions is: H2O -> PS II -> PS I -> NADPH.

Front

What are photosystems?

Back

Photosystems are protein-pigment complexes in the thylakoid membrane that capture light energy and convert it into chemical energy during photosynthesis.
