Cellular Respiration Review

Front

What is cellular respiration?

Back

Cellular respiration is a biochemical process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What are the main stages of cellular respiration?

Back

The main stages are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows glycolysis to continue by regenerating NAD+ in the absence of oxygen.

Front

What is the equation for cellular respiration?

Back

O2 + C6H12O6 -> CO2 + H2O + Energy.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.

Front

What is the Krebs Cycle?

Back

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

Front

What are the products of glycolysis?

Back

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

Front

What is the electron transport chain?

Back

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