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 (Citric Acid Cycle) 3. Electron Transport Chain

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 products of glycolysis are 2 ATP, 2 NADH, and 2 pyruvate molecules.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain, where they are used to generate ATP.

Front

What is the Krebs Cycle?

Back

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

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondrial matrix.

Front

What are the products of the Krebs Cycle?

Back

The products of the Krebs Cycle include ATP, NADH, FADH2, and CO2.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient.
