AP Biology Unit 3 Review

Front

Where does glycolysis take place?

Back

Cytosol

Front

Which step of cellular respiration REQUIRES oxygen?

Back

Oxidative phosphorylation

Front

What is the function of NADP+?

Back

It is an electron carrier.

Front

Describe the pathway of electrons in the light reactions.

Back

H₂O → PSII → ETC → PSI → NADPH

Front

Why does an increase in temperature increase the rate of a reaction?

Back

Increase in temperature increases the speed/kinetic energy of particles.

Front

What is the main purpose of glycolysis?

Back

To convert glucose into pyruvate, producing ATP and NADH.

Front

What are the end products of the Krebs cycle?

Back

CO₂, ATP, NADH, and FADH₂.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain.

Front

What is the primary function of the electron transport chain?

Back

To create a proton gradient that drives ATP synthesis.

Front

What is the significance of NADH and FADH₂ in cellular respiration?

Back

They are electron carriers that transport electrons to the electron transport chain.
