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 main purpose of glycolysis?

Back

The main purpose of glycolysis is to break down glucose into pyruvate, producing a small amount of ATP and NADH in the process.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 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 mitochondria of the cell.

Front

What are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are 2 ATP, 6 NADH, and 2 FADH2 per glucose molecule.

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.

Front

What role do electron carriers play in cellular respiration?

Back

Electron carriers like NADH and FADH2 transport electrons to the electron transport chain, facilitating ATP production.
