AP Biology Unit 3 Review

Front

What are the main electron carriers in the electron transport chain during cellular respiration?

Back

NADH and FADH2 are the main electron carriers in the electron transport chain.

Front

How many ATP molecules are produced during glycolysis?

Back

2 ATP molecules are produced during glycolysis.

Front

Where does the substrate bind on an enzyme?

Back

The substrate binds at the active site of the enzyme.

Front

Which molecule is not required for the Calvin Cycle?

Back

H2O is not required for the Calvin Cycle.

Front

Where do the light reactions occur and where does the Calvin Cycle take place?

Back

The light reactions occur in the thylakoid membrane, and the Calvin Cycle takes place in the stroma.

Front

What is the role of NADH in cellular respiration?

Back

NADH serves as an electron carrier, transporting electrons to the electron transport chain.

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 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.

Front

What is the significance of the active site on an enzyme?

Back

The active site is where the substrate binds, allowing the enzyme to catalyze a reaction.

Front

What are the products of glycolysis?

Back

The products of glycolysis are 2 pyruvate, 2 ATP, and 2 NADH.
