Cellular Respiration

Front

What is Cellular Respiration?

Back

A metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the primary energy carrier in cells?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells.

Front

What is the role of ADP in cellular respiration?

Back

ADP (Adenosine Diphosphate) is converted to ATP during cellular respiration, serving as a precursor to energy.

Front

What is Glycolysis?

Back

The first stage of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs Cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the Electron Transport Chain?

Back

A series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to produce ATP.

Front

What is the significance 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 Pyruvate?

Back

A three-carbon compound that is the end product of glycolysis and is further processed in the Krebs cycle.

Front

What is Acetyl-CoA?

Back

A two-carbon molecule that enters the Krebs cycle after being derived from pyruvate.

Front

What is Citric Acid?

Back

A six-carbon compound formed in the Krebs cycle, also known as citrate.
