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 are the three main stages of cellular respiration?

Back

The three main stages are Glycolysis, Krebs Cycle (Citric Acid Cycle), and Oxidative Phosphorylation.

Front

Where does glycolysis occur?

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 happens to pyruvate after glycolysis?

Back

Pyruvate is transported into the mitochondria, where it is converted into acetyl CoA before entering the Krebs Cycle.

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 are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are ATP, NADH, FADH2, and carbon dioxide.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the energy from electrons transferred through the electron transport chain.

Front

Where does oxidative phosphorylation occur?

Back

Oxidative phosphorylation occurs in the inner mitochondrial membrane.
