AP Biology: Unit 4 Cellular Energetics (Ryan)

Front

What is the function of decoupling oxidative phosphorylation in the electron transport chain?

Back

Generate heat to regulate body temperature in endotherms.

Front

Describe the pathway of electrons in the light reactions of photosynthesis.

Back

H2O → PSII → ETC → PSI → NADPH.

Front

Which molecule enters the Kreb's Cycle?

Back

Acetyl CoA.

Front

Where is the electrochemical gradient of protons generated in the electron transport chain of cellular respiration?

Back

Intermembrane space.

Front

What is the role of NADH and FADH2 in the electron transport chain?

Back

They donate electrons to the chain.

Front

What is oxidative phosphorylation?

Back

A process that uses energy from the electron transport chain to produce ATP.

Front

What is the primary purpose of the Kreb's Cycle?

Back

To produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

What is the role of ATP synthase in cellular respiration?

Back

To synthesize ATP from ADP and inorganic phosphate using the proton gradient.

Front

What is the significance of the proton gradient in cellular respiration?

Back

It drives ATP synthesis during oxidative phosphorylation.

Front

What are the end products of glycolysis?

Back

2 pyruvate, 2 ATP, and 2 NADH.
