AP Biology: Unit 4 Cellular Energetics (Ryan)

Front

What is the effect on free energy when the amount of enzyme is doubled?

Back

No effect on free energy.

Front

What is the final electron acceptor in the electron transport chain during aerobic respiration?

Back

Oxygen.

Front

What role does Rubisco play in photosynthesis?

Back

Carbon fixation when CO2 is connected to RUBP during the Calvin cycle.

Front

What are the two main components of oxidative phosphorylation?

Back

Electron transport chain & Chemiosmosis.

Front

Where does the Calvin cycle occur?

Back

Stroma.

Front

Define cellular respiration.

Back

The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is ATP and its role in cellular energetics?

Back

Adenosine triphosphate (ATP) is the primary energy carrier in cells.

Front

Explain the process of glycolysis.

Back

Glycolysis is the breakdown of glucose into pyruvate, producing ATP and NADH.

Front

What is the Krebs cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is chemiosmosis?

Back

The movement of ions across a selectively permeable membrane, down their electrochemical gradient, to generate ATP.
