AP Bio Insta-Review Topic 3.6*: Cellular Respiration

Front

What is the main purpose of cellular respiration?

Back

To convert glucose into ATP, providing energy for cellular processes.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain.

Front

Where does glycolysis occur in the cell?

Back

In the cytosol.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain.

Front

What is produced during the Krebs Cycle?

Back

ATP, NADH, FADH2, and CO2.

Front

What is the final electron acceptor in the electron transport chain?

Back

Oxygen (O2).

Front

What is ATP Synthase and its function?

Back

An enzyme that synthesizes ATP from ADP and inorganic phosphate during oxidative phosphorylation.

Front

How do prokaryotes perform cellular respiration differently from eukaryotes?

Back

Prokaryotes perform the electron transport chain on their plasma membrane, while eukaryotes do so in the mitochondria.

Front

What is the significance of the cristae in mitochondria?

Back

Cristae increase the surface area for ATP production during the electron transport chain.

Front

What is fermentation and when does it occur?

Back

Fermentation is an anaerobic process that occurs when oxygen is not available, allowing glycolysis to continue producing ATP.
