AP Biology - Cellular Respiration

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP, carbon dioxide (CO2), and water (H2O).

Front

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

Back

NADH and FADH2 are electron carriers that transfer electrons to the electron transport chain, facilitating ATP production.

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 the Krebs Cycle occur?

Back

The Krebs Cycle occurs in the mitochondrial matrix.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the electron transport chain, using the energy from electrons to pump protons and create a gradient.

Front

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

Back

The electrochemical gradient of protons is essential for ATP synthesis, as protons flow back into the mitochondrial matrix through ATP synthase, driving the production of ATP.

Front

What is the function of ATP synthase?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate, using the energy from the proton gradient.

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 role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of water and enabling the continuation of the process.

Front

What is the Citric Acid Cycle (Krebs Cycle)?

Back

The Citric Acid Cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
