Stages of Cellular Respiration

Vocabulary terms covering the stages, cellular locations, and key outcomes of cellular respiration.

Glycolysis

The stage of cellular respiration that occurs in the cytoplasm, splits glucose, and yields a net of $2$ ATP.

Prep reaction

The stage of cellular respiration located in the mitochondrial matrix in eukaryotic cells where pyruvate is converted, producing $CO_2$ and NADH.

Krebs/citric acid cycle

The stage of cellular respiration occurring in the mitochondrial matrix that releases $CO_2$ and produces NADH, $FADH_2$, and ATP.

Electron transport chain

The stage of cellular respiration located in the inner mitochondrial membrane that produces the most ATP.

Passive transport

Substances move down their concentration gradient from higher transport to LOWER transport.

Active Transport

Cell uses energy to move substances against their concentration gradient - from

lower to HIGHER concentration. (Requires energy) (passive does not)
