AP Bio Insta-Review Topic 3.6: Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the overall equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Front

What are the three main stages of cellular respiration?

Back

1. Glycolysis 2. Krebs Cycle 3. Oxidative Phosphorylation

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the main product of glycolysis?

Back

The main product of glycolysis is pyruvate, along with a small amount of ATP and NADH.

Front

What is the Krebs Cycle also known as?

Back

The Krebs Cycle is also known as the Citric Acid Cycle.

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondrial matrix.

Front

What is produced during the Krebs Cycle?

Back

The Krebs Cycle produces ATP, NADH, FADH2, and CO2.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the electron transport chain and chemiosmosis.

Front

Where does oxidative phosphorylation occur?

Back

Oxidative phosphorylation occurs in the inner mitochondrial membrane.
