Bio8 Vocab: Cellular Respiration

Front

Cellular Respiration

Back

The process by which cells break down glucose and other molecules to produce energy (ATP).

Front

ATP (Adenosine Triphosphate)

Back

The main energy currency of the cell.

Front

Glucose

Back

A simple sugar used as the primary fuel for cellular respiration.

Front

Mitochondria

Back

The organelle where most steps of cellular respiration occur.

Front

Aerobic Respiration

Back

Cellular respiration that requires oxygen to produce energy.

Front

Anaerobic Respiration

Back

Cellular respiration that does not require oxygen, producing less ATP.

Front

Glycolysis

Back

The first step of cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

Pyruvate

Back

A three-carbon molecule produced during glycolysis.

Front

Krebs Cycle (Citric Acid Cycle)

Back

The stage of aerobic respiration that breaks down pyruvate to produce electron carriers.

Front

Electron Transport Chain (ETC)

Back

The final stage of aerobic respiration where most ATP is produced.
